Liming Zhang · Fudan xuebao. Ziran Kexue ban · 2000
Fractal image compressing is a new image compression method based on fractal Iterated Function System (IFS). Although the method can achieve high compression, it will take long time to do image coding with high computational complexity. Fractal compression method combined with Discrete Cosine Transform (DCT ) approximation improves the precision of luminance shift so that high quality, high compression and less encoding time can be achieved. Several standard images are compressed by using three different methods and the results show that the new method is better than others.
