zero-tree structure 零树结构
This algorithm utilize wavelet zero tree structure to represent the correlation between scales, then classified wavelet modulus and adopt mixed-model approximation of part statistical characteristic of each type, realizing image noise reduction processing in the framework of Bayes.
该算法首先利用小波零树结构表达尺度间的相关性,将小波系数进行分类,然后采用混合模型逼近每类的局部统计特性,在贝叶斯框架下实现图像的降噪处理。
