Abstract:

This paper presents a similar use of non-local image denoising methods.Multiple initial denoising images with parameters close to each other are obtained using non-convex function threshold,and then similar images blocks are selected from these preliminary de-noising images for image denoising recovery by non-local averaging method.Experiment shows that the proposed method yields good results with better PSNR than typical non-local averaging methods.

Key words: threshold value;image denoising;nonlocal
