Webyears is the non-local means (NLM) algorithm [1]. Unlike most denoising algorithms that rely on the local regularity assumption, the NLM algorithm estimates an unknown pixel by a weighted average of local and non-local pixels throughout the entire image. The weight decreases exponentially with an increased distortion between the neighborhoods ...

It performs well for filtering Gaussian noise while preserving edges and details of the original images. In this paper, we propose an improved filter for color image denoising based on combining the advantages of non-local means filter and bilateral filter.
