Nonlocal means method (NLM) is a powerful algorithm in image denoising area. In this article, firstly its modified expression is defined, and then generalized cross validation (GCV) method is used to approximate the optimal value of two parameters in this expression. At the same time, the analytical formula of GCV method can also be derived from modified(More)
