统图像编码采用离散余弦变换(DCT)技术，可以较好地去除图像信息的统计冗余，具有良好的实时性和块操作与运动估计的匹配性。目前该技术日臻成熟，形成了JPEG、MPEG等国际标准。但是由于DCT变换过程采用分块技术，在高压缩比条件下容易导致方块效应，严重影响主观质量。而且DCT不适合带宽较宽(拥有较多边缘轮廓信息)的图像信号。于是人们将目光转向小波变换。 传统的卷积小波变换是一种不受带宽约束的图像处理方法，支持多分辨率、多码率传输方案，而且不对图像进行分块，避免了DCT变换的方块效应。但是，采用卷积运算方法，过程复杂，运算量大，实时性不好，不利于硬件的实现。而基于JPEG2000标准推荐的提升小波变换，采用9/7、5 /3滤波器组对分解的图像进行提升运算，不但继承了传统小波变换的优点，而且实时性好、运算简单、易于硬件实现。
