Analysis of low bit rate image transform coding

Analysis of low bit rate image transform coding

Calculations based on high-resolution quantizations prove that the distortion rate D(R) of an image transform coding is proportional to 2/sup -2R/ when R is large enough. In wavelet and block cosine bases, we show that if R
