Efficient implementation of a fractal color image compression on FPGA

Abstract

Fractal Image Compression (FIC) method provides a color image compression solution with an extremely high compression ratio, however it requires relative large amount of operations to complete codification. 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 YCrCb color transformation and suitable sampling modes, then implemented on FPGA board. The experimental results performed by Fisher's method for a color image have verified the possibility to design a SoC for fast fractal coder/decoder of a color image.
