In order to further improve the compression ratio of 12-bit static image,a static image compression scheme based on M encoder is presented.On the basis of JPEG standard coding framework,the 12-bit gray image quantization table is added in this compression scheme.The M encoder,which is the arithmetic coding engine of the CABAC is improved and used as the coder for static image compression.The compressed code stream is encapsulated in byte stream format,which is similar to those presented in H.264 and H.265.T...
