该文提出了一种能高品质重建图象的形态滤波器子带编码法,这种分解法具有实时性较好、通道错误不扩散、利于传输等特点;其重建图象与传统线性子带分解法相比,不会受振铃效应(ring effect)的影响.与ASD子带分解法相比,它的复杂度低,且采用了自适应压扩量化.通过与JPEG的比较显示,该方法在高保真压缩(压缩率约4倍)的情况下,其PSNR和视觉效果接近于JPEG,而在复杂度、抗通道错误鲁棒性方面则明显优于JPEG.

In this paper, we suggest a new subband compression schemes based on Morphological Subband Coding(MSC). Compared with the classical QMF subband filters, it will not be affected by ring effect. In contrast to ASD method, it is simple and adopts the adaptive companding quantization. Moreover, the result images compared with JPEG show that: with perfect reconstruction quality, MSC has better properties such as low complexity and high robustness on transmission.
