based on the method of block coding fractal image compression proposed by Jacquin

a new fractal color image compression method based on Vector Distortion Measure and Adaptive Quadtree Partiton is presented.This method fully exploits the correlation between the three color components of 24 bits true color image in RGB color space

experiments show that both compression ratio and reconstructed image quality are much better than that of separate fractal coding in RGB color images.
