According to the different coherent ratio between image,noise and over-complete dictionary,image information and noise are distinguished. One image adaptive filtering is realized by taking coherent ratio threshold as the condition to end the sparse decomposition process.
利用图像(或图像残余)和噪声与原子库相干性的不同,区分图像和噪声；以相干比阈值作为提取图像有用信息的结束条件,实现图像与噪声的自适应分离。
