| 摘 要： | 小波变换继承了傅立叶分析优点，主要使用在静态和动态图像压缩领域，已经成为某些图像压缩的国际标准。二维小波变换是在第一代图像压缩基础上，采用小波变换为主的多尺度分析算法，使处理后的图像可以达到30—60倍的高压缩比率，也更适合在目前低宽带的网络中传输。

| Abstract: | Small wave transform,taking advantage from Fourier analysis,is mainly used in static and dynamic picture compressing field,and become certain picture compressing international standard.Two-dimension small wave transform,based on the first generation of picture compressing,takes multi-scale ALG and makes the picture much higher reduction ratio rate of 30-60 times.It is suitable using in low wideband network. |
