BM3D算法源代码。NLM去噪算法使用的是inter-patchcorrelation，而Wavelet shrinkage使用的则是intra-patch correlation。这两种方法都取得了不错的效果，一个很自然的想法就是：可以同时使用他们两个方法吗？这便导出了BM3D去噪算法[2]，算是现在公认的去噪效果最好的算法。-BM3D algorithm source code. NLM Denoising algorithm using inter-patchcorrelation, and Wavelet shrinkage is the use of intra-patch correlation. Both of these methods have achieved good results, a very natural idea is: You can use them both ways? This has derived BM3D denoising algorithm [2], regarded now recognized as the best de-noising algorithm.
