摘    要:JPEG2000是基于小波变换的图像压缩技术,它不像传统的压缩技术,JPEG2000的良好的压缩效果取决于选取好的小波.嵌入式零树小波编码算法是基于小波变换的一种图像压缩方法,也是有相对不错的压缩效果。对此研究将以嵌入式零树小波为基础,改进其算法,实现在航天项目上的快速高效的压缩图像。

关 键 词:小波变换  嵌入式小波变换  嵌入式零树小波变换  图像压缩

Abstract:Wavelet-based image coders like the JPEG2000 standard are the state of the art in image compression.Unlike traditional image coders,however,their performance depends to a large degree on the choice of a good wavelet. EZW(Embedded Zerotree Wavelet) coding based on wavelet transform is a kind of image coding method that can reach a good result.In this paper,an Evolved algorithm that is based on EZW is proposed for improving the compression performance in spaceflight.
Keywords:wavelet transform  embedded wavelet  embedded Zerotree wavelet transform  image compression
