Fractal color image coding algorithm based on human visual system
Hongyuan Zheng · Journal of Computer Applications · 2009
By analyzing the traditional quadtree fractal coding algorithm, a Human Visual System (HVS) based fractal color image coding algorithm was presented in this paper. The feature of HVS was used to quadtree partition of range blocks. Classification method was also used to construct domain pool. Then the correlation of R,G,B components of a color image was used to merge three color components into one. The improved scheme above was used to search for the best domain block for each range block of the merged image. Experimental results indicate that the presented method in this paper has a higher compression ratio than Fisher s method and JPEG while remaining good reconstructured image quality, and it is faster than Fisher s method.
