之前我发了数篇系列博文来仔细研究Poisson Image Editing算法，每次重新审视和深入，仿佛都能有更为深刻的认识和很大的收获。这应该算是我这个系列的完结篇，会用用Matlab代码一点一点的演示，原文作者到底是如何设计和实现他那个强大且影响深远的算法的。希望你在看本文之前务必参考一下文章来了解算法原理，本文将主要讲解编程实现的问题，对于前面讲过的内容，我不会深究。-Before I sent a series of blog posts to carefully study the I

An extension of the non local (NL) means is proposed for images damaged by Poisson noise. The proposed method is guided by the noisy image and a pre-filtered image and is adapted to the statistics of Poisson noise. The influence of both images ca
