Abstract :
A novel paradigm for fractal coding selectively corrects the fractal code for selected domain blocks with an image-adaptive VQ codebook. The codebook is generated from the initial uncorrected fractal code and is therefore available at the decoder. An efficient trade-off results between incremental performance and bit rate
