Recently, the NLMeans Filter has been proposed by Buades et al. for the suppression of white Gaussian noise.This filter exploits the repetitive character of structures in an image, unlike conventional denoising algorithms, which typically operate in a local neighborhood.In this paper, we present an extension of this technique to the noise reduction of colored (correlated) noise, which is applicable in more realistic scenarios.Visual and PSNR results show a significant improvement in denoising performance compared to recent wavelet-based techniques.
