Abstract

Abstract: The paper presents the algorithm of the compression of image JPEG2000. It dissertates the problems such as the selection of the filters and the boundary problem in the algorithm and then researches the methods of the solution. The algorithm is demonstrated in the experiment.

Key words: Wavelet, Image compression, Mallat algorithm, Filter, Boundary processing

摘要： 论述了JPEG2000图像压缩的Mallat算法，对算法中滤波器的选择以及边界处理问题作了探讨并研究了解决方案。JPEG算法压缩产生了明显的方块效应，而该文算法有很好的效果，在实验中验证了算法。

关键词: 小波, 图像压缩, Mallat 算法, 滤波器, 边界处理
