Abstract

In traditional non-local mean value algorithm, both filter parameters and measurement of search neighborhood are constant globally and it does not show diverse structural features of different areas in images, which makes the weight of similarity of image blocks distributed unreasonably, and thus de-noising can be not effective. In order to avoid that, a non-local mean value image de-noising algorithm based on self-adaption is pro-posed. With analysis of the content of image blocks, image blocks from different areas will obtain different filter parameters and search fields, which cause the similarity weights of image blocks a more proper distribution. Experimental results showed that the new algorithm, after de-noising, achieved an increase of peak signal to noise ratio of images and, at the same time, reserved details of images and marginal information effectively.
