摘要

在设计用于子带编码系统的小波变换时，要考虑的一个问题是如何避免压缩图像中的环效应。我们开发了一种技术来最小化这种影响，使编码增益优化。我们设计了无副瓣小波，该条件是在满足一定的约束条件下得到的。我们将我们的结果与先前发表的一些小波进行了比较。

Minimizing ringing effect on images coded at low bit rates with wavelets

When designing wavelet transforms for subband coding systems, a problem of concern is to avoid ringing effects in the compressed images. We developed a technique to minimize this effect which enables for coding gain optimization. We design wavelets without sidelobes, a condition which is obtained when certain constraints are met. We compare our results to some previously published wavelets.
