小波变换在运动图像压缩编码中的最新进展

运动图像压缩编码技术是多媒体技术的重要组成部分，高效快速的算法研究一直是国际学术界和工业界关注的热点问题。小波变换以紧支撑、自适应和多分辨分析等性质以及对人眼视觉系统的良好模拟在运动图像压缩编码中可以较好地取代传统DCT变换方法，有着广阔的应用前景。文章首先分析了信号的MRA表示，接着讨论了小波分析在运动图像编码中的最新进展，最后得出了未来的研究方向和趋势。

Latest progress of wavelet transform in motive image coding

Motive image coding is an important part of multimedia techniques.Study on fast and high efficient algorithms has always been a hot question in international industry and academia.With the properties of compact support,self-adaptation,mutliresolution and good simulation of human eyes visual system wavelet transform can take the place of DCT transform with better performance in motive image compression coding and has a brilliant future.This paper first analyses MRA representation of signals.And then describes the latest progress of wavelet transform in it in detail.At last it points out the direction and trend of the study on wavelet transform in motive image coding.
