Random NL-Means to Restoration of Colour Images

Abstract

In this paper we propose a new method of denoising of colour images. We use non local means algorithm considered on non square searching window which is driven by anisotropic stochastic process. This modification allow us to adapt the idea from famous non local means and anisotropic diffusion approaches. Experimental results show that this new method gives encouraging results and can be successfully applied to denoising of high ISO images.
