Abstract

Fractal coding of digital images offers many promising qualities. However the coding process suffers from the long search time in the Domain Block Pool. We present a novel idea for speeding up search and improving compressive ratio, based on the hypothesis that those correlative Range Blocks should have a common code. Experimental result on 512 X 512 Lenna image is 32.8 dB at 0.625 b/pixel and 29.76 dB at 0.214 b/pixel.
