阅读说明：本技术 模式信息的编码和解码方法、装置以及电子设备 (Mode information encoding and decoding method and device and electronic equipment ) 是由 徐张磊 朱建清 于 2017-12-06 设计创作，主要内容包括：一种模式信息的编码和解码方法、装置以及电子设备。所述编码方法包括：确定图像的编码单元所采用的均匀变换单元模式；根据所述编码单元的大小和/或预先确定的均匀变换单元模式的数目,确定所述均匀变换单元模式所对应的二进制比特；以及将所述均匀变换单元模式所对应的二进制比特编码到所述图像的比特流中。由此,不仅能够对均匀变换单元模式信息进行编码和解码,并且能够降低编码的比特代价。(A method and a device for encoding and decoding mode information and an electronic device. The encoding method comprises the following steps: determining a uniform transform unit mode adopted by a coding unit of an image; determining binary bits corresponding to the uniform transformation unit modes according to the size of the coding unit and/or the number of the predetermined uniform transformation unit modes; and encoding the binary bits corresponding to the uniform transform unit mode into a bitstream of the image. Thereby, not only uniform transform unit mode information can be encoded and decoded, but also bit cost of encoding can be reduced.)
