基于多小波变换的矢量量化图象快速编码算法

A Fast Image Encoding Algorithm for Vector Quantization Based on Multi-Wavelet Transforms

提出了一种基于多小波变换的矢量量化编码算法,图象的多小波变换优于普通小波变换,此算法又加快了编码速度。实验表明计算时间有所减少,峰值信噪比有所提高,且图象无明显块效应。

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.
