Transform coding of DCT coefficients in video encoder
The redundancy among discrete cosine transform（DCT） coefficients in video encoder was found very strong,a method for subband decomposition and transform coding was proposed.Each 8×8 DCT spectrum date of macroblock was regrouped to gather the same frequency bands.The Hadamard transform function was u...
