Abstract:A fast comp ression algorithm of Iris image interest region based on symmetry and fractal coding is p roposed by using its inherent symmetry feature. The matched domain image blocks are restricted in the symmetri2 cal region for a range block, which can decrease the searching region of the blocks, then speed up the fractal enco2 ding, at last, accelerate the Iris image comp ression.
