Fast FPGA implementation of YUV-based fractal image compression

Abstract

Fractal Image Compression (FIC) method provides a color image compression solution with an extremely high compression ratio and an relatively good PSNR. In this paper, we have developed an efficient approach for a fractal image compression applied to a color image, which utilizes a fractal coding on RGB to YUV color transformation at 4:1:1 sampling mode. The experimental results performed by Fisher's method for a color image have verified the possibility to increase the compression ratio of FIC for color image while retaining an acceptable PSNR. It's purposed to design the low-bit-rate video encoding system by fractal coder/decoder of a color image.
