基于整数小波变换的静态图像压缩编码技术

Techniques of Still Image Compress Coding Based on Integer Wavelet Transform

目前多媒体和Internet技术的迅猛发展导致了人们对图像编码有了越来越高的要求。由于小波变换所具有的一些特性非常符合图像处理的要求,使得小波变换图像编码得到了广泛关注。本文结合小波变换的特点,对几种经典的小波图像编码算法进行了讨论,并对静止图像编码的研究方向进行了展望。

With the fast development of multimedia and Internet technology, more and more requirements on image coding are proposed. Some characteristics of wavelet transform are greatly accorded with the requirement of image processing, which has caught much attention to wavelet image coding. In this paper, some classical algorithms of wavelet image coding are studied to link with the characteristic of wavelet transform and the future development of image coding is also analyzed and conjectured.
