A Novel Improved Algorithm of Image Fractal Compression
Zhou Xingmin · Dianzi xuebao · 2003
The paper analyses the weakness of traditional speed-up techniques for image fractal compression firstly,and proposes a novel idea by using entropy to improve image fractal compress performance.A theorem is proved that the IFS cannot change the image blocks' entropy values.Moreover,it gives a novel fractal compression method based on entropy and its extension.The simulation results illuminate that the new method can improve the PSNR,compress ratio and compress time cost.
