i have read the image and encoded using 4*4 DCT and now i am having the DC and 15 AC coefficients.Then to reduce the range of DC coefficients i did differential encoding..I have read the 4*4 subsampled image and now how can i represent the intermediate DC n AC coefficients in to bitstreams which helps me to identify the compression ratio ? For example..59 0 1 -1 0 0 -1 -1 1 -1 0 0 -1 0 1 0 i want to do variable encoding for this to get bit stream...
