我们知道，图像压缩就是要寻找高压缩比、并使压缩后的图像有合适的信噪比的方法，对压缩后的图像还要能实现低失真度地恢复图像。压缩性能的评价标准之一是图像能量损失和零系数成分值。能量损失越小，零系数成分值越大，图像压缩的性能就越高。 -We know that image compression is to find a high compression ratio, and the compressed image signal to noise ratio suitable metho

Actual applications require specifi c methods to reduce the infl uence of the correlation to distortions that appear when input images differ from their reference model. When the distortion model can be described analytically (such as
