Detailed Description

The purpose of early image processing was to improve the quality of images, which were targeted at human subjects with the aim of improving human visual effects. In image processing, an image with low quality is input, an image with improved quality is output, and common image processing methods include image enhancement, restoration, encoding, compression, and the like. The first practical successful application was the Jet Propulsion Laboratory (JPL) in the united states. The astronautic detector 7 sends thousands of lunar photographs back in 1964 to a spaceflight detector loitering person by using image processing technology, such as geometric correction, gray level transformation, noise removal and the like for processing, and the lunar surface map is successfully drawn by a computer by considering the influence of the sun position and the lunar environment, so that great success is achieved. Then, more complex image processing is carried out on nearly one hundred thousand photos sent back by the exploration spacecraft, so that a topographic map, a color map and a panoramic mosaic of the moon are obtained, extraordinary achievements are obtained, a solid foundation is laid for the creation of a human landing on the moon, and the birth of a subject of digital image processing is promoted. In the future space technology, such as the detection research of the mars such as mars and saturns, the digital image processing technology plays a great role. Another huge achievement gained by digital image processing is the medically gained effort.
