CORRELATION ANALYSIS OF DISCRETE COSINE TRANSFORM COEFFICIENTS OF IMAGE BLOCKS
Task of lossy image compression based on discrete cosine transform (DCT) is considered. For image blocks having size 8x8 pixels (it corresponds to division of images on blocks in JPEG standard) presence of correlation between different DCT coefficients of the same block as well as between coefficien...
