The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The embodiment will be described from the perspective of a virtual article display apparatus, which may be specifically integrated in an electronic device, where the electronic device may include a mobile phone, a tablet Computer, a notebook Computer, a terminal, a Personal Computer (PC), and other devices.

A virtual item display method, comprising: receiving a virtual article sending instruction, wherein the virtual article sending instruction carries a virtual article identifier, then acquiring an article image and a target dynamic effect video which form a virtual article based on the virtual article identifier, wherein the target dynamic effect video comprises at least one video frame, then determining position information of each pixel point in an article image fusion area in the video frame, then acquiring pixel information of a corresponding position in the article image according to the position information, fusing the pixel information and the pixel information of the corresponding position in the target dynamic effect video to obtain a virtual article dynamic effect video, and then sending the virtual article dynamic effect video to a terminal of a target object for dynamic effect display of the virtual article.

As shown in fig. 1b, the specific flow of the virtual article display method may be as follows:

101. and receiving a virtual article sending instruction, wherein the virtual article sending instruction carries a virtual article identifier.

The virtual article sending instruction may carry a virtual article identifier. The virtual article identifier refers to information that can be used to identify a virtual article, such as a number or a code of a virtual cake, a virtual flower, a virtual duck, and the like, and specifically may be an Identity Document (ID) of the virtual article.

The virtual object is a non-physical object and an invisible object. The other production mode and the other production field are visible and untouchable and are a product of the virtual world. For example, the virtual gift may be sent through a network, such as a virtual flower, cake, etc. sent to a friend or stranger, a gift sent to a main broadcaster when watching a live broadcast, or an item derived from a virtual network game world, such as equipment, a weapon, etc.

The virtual article sending instruction may be generated by the virtual article display device receiving a virtual article request sent by a user, or may be generated by other devices, such as a terminal, after receiving the virtual article request sent by the user, and then provided to the virtual article display device, that is, the virtual article display device may specifically receive the virtual article sending instruction, and may also receive the virtual article sending instruction sent by other devices.

For example, a user interaction page may be displayed, the user interaction page including a virtual article selection control, the virtual article selection page being displayed when a triggering operation of the user on the virtual article selection control is detected, and the virtual article sending instruction being received when the user sends an operation on a virtual article of the virtual article selection page.

The representation form of the control can be in the form of an icon, an input box, a button and the like. For example, a user interaction page for a user to communicate with a target object may be specifically displayed on a terminal of the user, the user interaction interface may include a virtual article selection button, for example, a "know-want" button in friend making software, the user may perform a trigger operation on the button, such as clicking, sliding, or the like, when the terminal detects the trigger operation of the user on the virtual article selection control, a virtual article selection page may be displayed, in the virtual article selection page, the user may select a gift that is desired to be sent to the target object, for example, the virtual article selection page may include a virtual article switching control, such as a refresh button, a switching button, and the like, and when the user performs a trigger operation on the virtual article switching control, a different virtual article may be switched for the user to select. When a user performs a triggering operation on a virtual article sending control of the virtual article selection page, the virtual article displayed on the current virtual article selection page is determined to be a gift to be sent to a target object by the user, at this time, a virtual article sending instruction can be triggered, and the terminal receives the instruction. The target object refers to an object to which the user wants to send the virtual item, for example, the target user.

102. And acquiring an article image and a target dynamic effect video which form the virtual article based on the virtual article identification, wherein the target dynamic effect video comprises at least one video frame.

For example, based on the virtual article identifier, an animation component may be used to load an article image and a target animation video that constitute a virtual article, where the animation component includes a decoder, and the decoder is used to parse the target animation video to obtain at least one video frame.

The target animation video refers to a video which is intended to show a specific animation special effect on a virtual article, the target animation video may be bound with an article image in advance in a one-to-one correspondence manner and stored in a device, or may be selected by a user in a personalized manner according to the preference of the user, and the like, which is not limited herein. The animation fusion special effect of the virtual article can be realized by a video file with animation effect (namely a target dynamic effect video), a target image (such as an article image) needing to be fused into a video frame and a JavaScript file defining specific fusion logic.

The JavaScript (JS or JS for short) is a lightweight, interpreted, or just-in-time programming language with function priority. Although it is named as a scripting language for developing Web pages, it is also used in many non-browser environments, JavaScript is based on prototypical programming, multi-modal dynamic scripting languages, and supports object-oriented, imperative, and declarative (e.g., functional programming) styles.

For example, as shown in fig. 1c and 1d, an animation component may be used to load a service animation resource, that is, a js animation logic, an animation material, and an animation-related video file, then, a js rendering engine inside the animation component is used to interpret a js code, the js rendering engine is used to load the animation resource, the js animation logic is analyzed, and an Open Graphics Library (OpenGL) or a Metal is used to load an object image to obtain corresponding texture data, that is, a target texture corresponding to the object image. An internal decoding module (i.e., decoder) is called to load a video file related to the animation, such as a target animation video, and the video file can be decoded by using AVFoundation or FFmpeg to obtain at least one video frame. Therein, a video frame may be divided into two equal regions: an animation special effect area and a position information area of the fusion target texture.

Among them, the open graphics library is a cross-language, cross-platform Application Programming Interface (API) for rendering 2D, 3D vector graphics. This interface consists of nearly 350 different function calls to draw from simple graphics bits to complex three-dimensional scenes. Metal is a brand-new technology, specially created for developers who develop high-presence host games, and can make the developers fully exert the performance of the A7 and A8 chips. The technique is optimized to enable the processor and the graphics processor to work cooperatively to achieve optimal performance. It is designed specifically for multithreading and provides various excellent tools to integrate all material in Xcode. The Metal is a low-level rendering application programming interface, provides the lowest level required by software, and ensures that the software can run on different graphic chips.

Among these, AVFoundation is the iOS's own framework for processing audio-video frames, such as audio-video codec, etc., which can be used to play and create one of several frameworks of time-based audio-visual media, which provides an OC interface over a detailed interface of time-based audio-visual data. It can be used to examine, create, edit, re-encode media files. An advanced OC framework for manipulating video during real-time capture playback and processing of time-based media data is also available from the device. The advantages of multi-core hardware are fully utilized, and a large number of block and multi-thread programming (GCD) mechanisms are used for putting complex computing processes into background threads to run. Hardware acceleration is automatically provided to ensure that applications run at optimal performance on most devices.

The FFmpeg is a frame of a real audio and video frame which is open-sourced by a third party, and is a set of open-sourced computer programs which can be used for recording and converting digital audio and video and can convert the digital audio and video into streams. LGPL or GPL licenses are used. It provides a complete solution for recording, converting and streaming audio and video. It contains a very advanced audio/video codec (libavcodec), in which many codes are developed from scratch in order to guarantee high portability and codec quality. The FFmpeg multimedia video processing tool has very powerful functions including video capture function, video format conversion, video capture, watermarking of video, etc.

The programmable part in fig. 1c is js service logic code for implementing specific animation effects, controlling specific effects of video frames, such as video frame transparent processing, synthesizing video frames, and the like. For example, js1 and js2 represent different js animation logics, and the js rendering engine can select different js animation logics according to the video fusion requirement.

103. And determining the position information of each pixel point in the article image fusion area in the video frame.

The location information may include global location information and relative location information. For example, pixel recognition may be performed on the animation fusion region, an article image fusion region in the animation fusion region is determined, global position information of each pixel point in the article image fusion region in the animation fusion region is calculated, and relative position information of each pixel point in the article image fusion region is calculated.

For example, an article image fusion region in the video frame may be determined, and position information of each pixel point in the article image fusion region may be calculated, for example, each pixel point in the animation fusion region may be specifically identified by using an RGBA value of the pixel to determine the article image fusion region in the animation fusion region, and then position information of each pixel point in the article image fusion region is calculated.

Where RGBA is a color space representing Red (Red) Green (Green) Blue (Blue) and Alpha. Although it is sometimes described as a color space, it is actually just the RGB model with the additional information added. The color used is RGB, which can belong to any RGB color space, but Catmull (name of a person) and Smith (name of a person) propose this indispensable alpha value between 1971 and 1972, making alpha rendering and alpha synthesis possible.

The alpha channel (alpha channel) is typically used as the opacity parameter. If a pixel has an alpha channel value of 0%, it is completely transparent (i.e., invisible), and a value of 100% means a completely opaque pixel (a conventional digital image). A value between 0% and 100% allows the pixel to be displayed through the background, as though it were through glass (translucency), which effect is simply binary transparency (transparent or opaque) does not. It facilitates digital synthesis. The alpha channel values may be expressed in percentage, integer, or real numbers from 0 to 1 as with the RGB parameters.

For example, the relative position information of the pixel point can be determined by calculating the relative percentage of the pixel point in each direction, for example, the 2D image can calculate the x and y directions, and the 3D image can calculate the x, y and z directions, and the like.

For example, the percentage of each pixel point in the item image fusion region in the first direction in the item image fusion region may be specifically calculated, the percentage of each pixel point in the item image fusion region in the second direction in the item image fusion region may be calculated, and the relative position information of the pixel point in the item image fusion region may be determined according to the percentage of the first direction and the percentage of the first direction.

104. And acquiring pixel information of a corresponding position in the article image according to the position information, and fusing the pixel information and the pixel information of the corresponding position in the target dynamic effect video to obtain the virtual article dynamic effect video.

For example, the position information of the pixel point in the article image in the first direction may be determined according to the percentage of the first direction and the length of the article image, the position information of the pixel point in the article image in the second direction may be determined according to the percentage of the second direction and the width of the article image, and the pixel information of the corresponding position may be obtained based on the position information in the first direction and the position information in the second direction.

The pixel information may refer to color information, brightness information, and/or gray scale information of the pixel point, such as a pixel value. The pixel value is a value given by a computer when the document image is digitized.

For example, a js engine may be used to perform image processing on a video frame and a target texture to obtain an animation effect texture with a final effect, that is, a virtual article animation effect video, for example, the identified relative position information may be used to sample the target texture to obtain a pixel value of a corresponding point, the pixel value is replaced with the pixel value of the corresponding point in the original video frame, and the same technique is applied to other pixel points to finally blend other image materials (such as an article image) into the video frame, so as to achieve the effect of blending animation.

For example, pixel information of a corresponding position in the article image may be specifically obtained according to the relative position information, the global position information is mapped to the animation special effect region to obtain a corresponding pixel point in the animation special effect region, and the pixel information of the corresponding pixel point in the animation special effect region are fused to obtain a virtual article dynamic effect video.

In order to eliminate edge sawteeth appearing when pixels are fused into a video frame, smoothing can be performed on edge pixel points, for example, a user-defined filtering algorithm is applied when target textures are sampled, for example, whether the pixel points of an article image are located at the edge of the article image can be specifically judged, if the pixel points are located at the edge of the article image, fusion processing is performed on the pixel information of the pixel points to obtain fused pixel information, the fused pixel information is used for replacing the pixel information of the corresponding position in the target dynamic effect video to obtain a virtual article dynamic effect video, and if the pixel points are not located at the edge of the article image, the pixel information is used for replacing the pixel information of the corresponding position in the target dynamic effect video to obtain the virtual article dynamic effect video.

There are many ways to determine whether a pixel point of the article image is located at the edge of the article image, for example, whether the pixel point is located at the edge can be determined by an adjacent pixel point of the pixel point, and so on. The adjacent pixels can be the upper, lower, left and right pixels of the pixel, or the pixels in the east, south, east, west, north and east directions, and the like.

For example, as shown in fig. 1e, pixel information and position information of each pixel point in the article image may be specifically obtained, an adjacent pixel point of the pixel point is determined based on the position information, the pixel information of the adjacent pixel point is obtained, and whether the pixel point is located at the edge of the article image is determined according to the pixel information of the pixel point and the pixel information of the adjacent pixel point. Then, respectively determining the pixel value of the pixel point and the adjacent pixel value of the adjacent pixel point according to the pixel information of the pixel point and the pixel information of the adjacent pixel point, calculating the average value of the pixel value and the adjacent pixel value, carrying out fusion processing on the pixel value and the average value to obtain fused pixel information, and replacing the pixel information of the corresponding position in the target dynamic effect video by utilizing the fused pixel information to obtain the virtual article dynamic effect video.

The method for obtaining the pixel information and the position information of each pixel point in the article image may be various, for example, the article image may be loaded by using an open graphic library to obtain a target texture corresponding to the article image, and the target texture is sampled to obtain the pixel information and the position information of each pixel point.

In order to present the virtual article motion effect video on the video in a transparent form, a transparent processing technology of a video frame can be utilized to achieve a transparent animation effect to solve the problem of occlusion, for example, a non-article image fusion area in the target motion effect video can be specifically obtained, and each pixel point in the non-article image fusion area is set as a transparent pixel point.

105. And sending the virtual article dynamic effect video to a terminal of a target object to perform dynamic effect display of the virtual article.

For example, after the virtual article motion effect video is generated, the virtual article motion effect video may be directly sent to the terminal of the target object, or the virtual article motion effect video may be stored in the server, so that the server sends the virtual article motion effect video to the terminal of the target object, so as to perform motion effect display of the virtual article in the terminal of the target object, or simultaneously display the virtual article on the terminal of the user while sending the virtual article motion effect video, and so on.

In this case, an interface for displaying an animation effect, such as raantimationview (animation view interface), may be utilized, and the video frame output by the rendering engine is finally projected onto the display interface to display the final specific effect.

As can be seen from the above, this embodiment may receive a virtual article sending instruction, where the virtual article sending instruction carries a virtual article identifier, then obtain an article image and a target dynamic effect video that form a virtual article based on the virtual article identifier, where the target dynamic effect video includes at least one video frame, determine location information of each pixel point in an article image fusion region in the video frame, then obtain pixel information of a corresponding location in the article image according to the location information, fuse the pixel information with pixel information of a corresponding location in the target dynamic effect video, obtain a virtual article dynamic effect video, and then send the virtual article dynamic effect video to a terminal of a target object for dynamic effect display of the virtual article. According to the scheme, the combination of animation effects can be realized by utilizing pixel identification and fusion, rich animation effects are provided, elements in a video frame can be replaced and synthesized, multiplexing can be realized under similar use scenes, the problem of low efficiency under similar scenes is solved, and meanwhile, the customized characteristic and rich and personalized visual effects are achieved. The transparent animation effect is realized by utilizing the transparent processing technology of the video frame to solve the shielding problem, and the visual experience of a user is improved. According to the scheme, after the user selects the virtual article, the virtual article can be presented on the video in a transparent animation mode, a new animation effect can be formed by fusion with a background dynamic effect and presented on the video, a user-defined filtering algorithm is applied when target textures are sampled, edge sawteeth appearing when pixels are fused into video frames are eliminated, the richness of virtual article display is effectively improved, and the visual effect is improved.

The method described in the previous embodiment is further detailed by way of example.

In this embodiment, the virtual article display device is specifically integrated in an electronic device, an article image of a virtual article is a duck image, and a target dynamic effect video is a firework video.

As shown in fig. 2a, a virtual article display method may specifically include the following processes:

201. the electronic device displays a user interaction page that includes a virtual item selection control.

For example, the electronic device may specifically display a user interaction page for the user to communicate with the target object, and the user interaction page may include a virtual item selection control, for example, as shown in fig. 2b, a "know-want" button, which may be clicked by the user.

202. When the triggering operation of the user for the virtual article selection control is detected, the electronic equipment displays a virtual article selection page.

For example, specifically, when the electronic device detects a triggering operation of the user on the virtual article selection control, for example, a click operation is performed on a "know-want" button, a virtual article selection page is displayed, as shown in fig. 2c, the virtual article selection page may include a virtual article switching control, for example, a refresh button, and the user may switch a different virtual article, for example, a gift, by clicking the refresh button, as shown in fig. 2d, from which a virtual article that is desired to be sent to the target object is selected.

203. When the user selects the virtual item sending operation of the page for the virtual item, the electronic equipment receives a virtual item sending instruction.

For example, the virtual item selection page may include a virtual item sending control, which may be a "send" button as shown in fig. 2c, and specifically, when the user performs a triggering operation on the virtual item sending control of the virtual item selection page, for example, a click operation is performed on the "send" button, it is determined that a virtual item, such as a duck, displayed on the current virtual item selection page is used as a gift to be sent to a target object by the user, at this time, a virtual item sending instruction may be triggered, the electronic device will receive the instruction, and the virtual item sending instruction may carry a virtual item identifier.

204. The electronic equipment acquires an article image and a target dynamic effect video which form the virtual article based on the virtual article identification, wherein the target dynamic effect video comprises at least one video frame.

For example, the electronic device may load, based on the virtual article identifier, an article image (e.g., a duck image) and a target animation video (e.g., a firework animation video) that constitute the virtual article by using an animation component, and a js animation logic, interpret js codes by using a js engine inside the animation component, and call a decoding module inside the animation component to parse the firework animation video to obtain at least one video frame. Therein, a video frame may be divided into two equal regions: an animation special effect area and a position information area of the fusion target texture. And loading the duck image by utilizing OpenGL to obtain the target texture corresponding to the duck image.

205. And the electronic equipment carries out pixel identification on the animation fusion area and determines an article image fusion area in the animation fusion area.

For example, as shown in fig. 2e, the position of the target texture in the animation fusion region may be marked with a solid color block, and the electronic device may specifically identify each pixel point in the animation fusion region by using the RGBA value, for example, pixel scan identification may be performed by using underlying Graphics Processing Unit (GPU) hardware to determine a duck image fusion region in the animation fusion region, such as a solid color small block in the middle of the animation fusion region in fig. 2 e.

206. And the electronic equipment calculates the position information of each pixel point in the article image fusion area.

The location information may include global location information and relative location information. For example, the electronic device may calculate global position information of each pixel point in the duck image fusion region in the animation fusion region, for example, as shown in fig. 2e, when a pixel point in the duck image fusion region is identified, coordinate information of the pixel point in the animation fusion region is calculated, such as a pixel point a (x0, y0), and the pixel point a is mapped to the left animation special effect region to obtain coordinate information of a C point (x2, y2), where the C point is a pixel point to be fused.

Then, the electronic device can calculate the relative position information of each pixel point in the duck image fusion area. For example, the percentage of each pixel point in the duck image fusion region in the first direction in the duck image fusion region may be specifically calculated, for example, the percentage in the x direction, the percentage of each pixel point in the duck image fusion region in the second direction in the duck image fusion region may be calculated, for example, the percentage in the y direction, and the relative position information of the pixel point in the duck image fusion region may be determined according to the percentage in the first direction and the percentage in the first direction.

207. And the electronic equipment acquires pixel information of a corresponding position in the article image according to the position information.

For example, the electronic device may determine the position information of the pixel point in the first direction in the duck image according to the percentage of the first direction and the length of the duck image, determine the position information of the pixel point in the second direction in the duck image according to the percentage of the second direction and the width of the duck image, obtain the pixel information of the corresponding position in the duck image based on the position information in the first direction and the position information in the second direction, for example, map the a point to the duck image to obtain the position information of the B point (x2, y2), sample the target texture of the duck image to obtain the RGBA pixel information of the B point in the target texture.

208. And the electronic equipment fuses the pixel information and the pixel information of the corresponding position in the target dynamic effect video to obtain the virtual article dynamic effect video.

For example, the electronic device may obtain pixel information of a corresponding position in the duck image according to the relative position information, map the global position information to the animation special effect region to obtain a corresponding pixel point in the animation special effect region, fuse the pixel information with the pixel information of the corresponding pixel point in the animation special effect region, and perform the operations of step 205 to step 208 on each frame of video frame until all the video frames are processed to obtain the virtual article motion effect video.

For example, in order to eliminate edge jaggies occurring when pixels are fused into a video frame, smoothing may be performed on edge pixel points, for example, a user-defined filtering algorithm is applied when sampling a target texture, for example, the electronic device may specifically obtain pixel information and position information of each pixel point in a duck image, determine an adjacent pixel point of the pixel point based on the position information, obtain pixel information of the adjacent pixel point, and determine whether the pixel point is located at an edge of the duck image according to the pixel information of the pixel point and the pixel information of the adjacent pixel point. For example, whether the pixel point is at the edge of the target texture may be determined according to whether the pixel-based alpha channel is less than 1.

If the pixel point is located at the edge of the duck image, respectively determining the pixel value of the pixel point and the adjacent pixel value of the adjacent pixel point according to the pixel information of the pixel point and the pixel information of the adjacent pixel point, calculating the average value of the pixel value and the adjacent pixel value, fusing the pixel value and the average value to obtain fused pixel information, and replacing the fused pixel information with the pixel information of the corresponding position in the firework dynamic effect video to obtain the virtual article dynamic effect video. And if the pixel point is not positioned at the edge of the duck image, replacing the pixel information of the corresponding position in the firework dynamic effect video with the pixel information to obtain the virtual article dynamic effect video.

For example, as shown in fig. 1e, a southeast pixel ES, a southwest pixel WS, a northwest pixel WN, and a northeast pixel EN of the pixel M can be taken as the neighboring pixels. Then, calculating an average value of pixel values of the pixel point M, the southeast pixel point ES, the southwest pixel point WS, the northwest pixel point WN and the northeast pixel point EN, and fusing the pixel value and the average value of the pixel point M to obtain fused pixel information. For example, as shown in fig. 2f, before and after the filtering and smoothing process, fig. 2f (1) is an effect diagram of the pixel point before the smoothing process is performed by applying the customized filtering algorithm, and fig. 2f (2) is an effect diagram of the pixel point after the smoothing process is performed by applying the customized filtering algorithm.

The part of codes for eliminating the edge saw teeth generated by fusing the pixels into the video frame by applying the self-defined filtering algorithm can be as follows:

in order to present the virtual article motion effect video on the video in a transparent form, the electronic device may utilize a transparent processing technology of the video frame to achieve a transparent animation effect to solve the problem of occlusion, for example, the electronic device may specifically obtain a non-duck image fusion region in the firework motion effect video, set each pixel point in the non-duck image fusion region as a transparent pixel point, and set each pixel point in a non-solid block region of the animation fusion region as a transparent pixel point as shown in fig. 2 e.

209. And the electronic equipment sends the virtual article dynamic effect video to a terminal of the target object.

For example, in order to multiplex the obtained virtual article motion effect video in a similar usage scenario and improve efficiency, the electronic device may store the virtual article motion effect video in its own memory, or store the virtual article motion effect video in the server, so that the server sends the virtual article motion effect video to the terminal of the target object, so as to perform motion effect display of the virtual article in the terminal of the target object, or simultaneously display the virtual article on the terminal of the user while sending the virtual article motion effect video, and so on. For example, after the user clicks 'send', the duck gift can be presented on the video by the animation in the transparent form, and can also be fused with the background dynamic effect firework effect to form a new animation effect to be presented on the video, as shown in fig. 2g, the duck is sprayed upwards along with the fireworks to be scattered, and the duck itself also moves upwards and slowly becomes larger, just like the effect of spraying a dynamic duck in the fireworks.

As can be seen from the above, this embodiment may receive a virtual article sending instruction, where the virtual article sending instruction carries a virtual article identifier, then obtain an article image and a target dynamic effect video that form a virtual article based on the virtual article identifier, where the target dynamic effect video includes at least one video frame, determine location information of each pixel point in an article image fusion region in the video frame, then obtain pixel information of a corresponding location in the article image according to the location information, fuse the pixel information with pixel information of a corresponding location in the target dynamic effect video, obtain a virtual article dynamic effect video, and then send the virtual article dynamic effect video to a terminal of a target object for dynamic effect display of the virtual article. According to the scheme, the combination of animation effects can be realized by utilizing pixel identification and fusion, rich animation effects are provided, elements in a video frame can be replaced and synthesized, multiplexing can be realized under similar use scenes, the problem of low efficiency under similar scenes is solved, and meanwhile, the customized characteristic and rich and personalized visual effects are achieved. The transparent animation effect is realized by utilizing the transparent processing technology of the video frame to solve the shielding problem, and the visual experience of a user is improved. This scheme makes the user after selecting virtual article, and virtual article not only can present on the video with the animation of transparent form, can also move the effect with the background and fuse and form new animation effect and present on the video, for example, virtual article duck upwards sprays along with fireworks and scatters, and duck self also upwards moves and slowly grow, just like the effect of spouting a dynamic duck in the fireworks. When the target texture is sampled, a user-defined filtering algorithm is applied, edge sawteeth generated when pixels are fused into video frames are eliminated, the richness of virtual article display is effectively improved, and the visual effect is improved.
