An improved non-local denoising algorithm
TLDR
We show that the NLMeans algorithm is basically the first iteration of the Jacobi optimization algorithm for robustly estimating the noise-free image. Expand

A fast non-local image denoising algorithm
TLDR
In this paper we propose several improvements to the original non-local means algorithm introduced by Buades et al. which obtains state-of-the-art denoising results. Expand

A GPU-Accelerated Real-Time NLMeans Algorithm for Denoising Color Video Sequences
TLDR
In this paper, we go one step further and incorporate both temporal information and color information into the NLMeans algorithm, in order to restore video sequences. Expand
