We propose a new method for noise method used to estimate the performance of digital image denoising methods and compare. We first noise, a denoising algorithm calculation and analysis method called partial smoothing filter. Secondly, we have proposed a new algorithm based on all the pixels in the image non-local average, the non-local average (NL-means). Finally, we show several groups of experiments comparing non-local averaging algorithm and the local smoothing filter algorithm.
