| Abstract: | This paper proposes an image encoding algorithm for vector quantization based on Multi-wavelet transforms. Multi-wavelet is better than simple wavelet transforms and the algorithm also accelerates the speed of encoding.The experience shows that computing time is reduced;PSNR is raised and there is no clearly block effecting. |
