The article introduces the basic idea of the image denoising research,then describes a non-local means denoise algorithms.Finally,it uses MATLAB R2008a to achieve the noise reduction effect of the non-local mean noise reduction algorithm under the different standard deviation,and assessment this algorithm with structural similarity and peak signal to noise,lists the image denoise processing results and evaluation criteria for data.On this basis,it finds the image denoising algorithm that suitable for human visual system.
