| Abstract: | Image denoising by non-local means has been well acknowledged as an important approach to image denoising in recent years. This paper presents an overview of sparse model denoising based on Non-local means denoising research and analysis of recent domestic and abroad literatures. To begin with, this paper reviews the development of Non-local means research, then summarizes several methods in procedure of Non-local means denoising, and finally points out the problems and future directions of Non-local means denoising method. |

| Keywords: | image denoising non-local mean similar patch wavelet denoising low-rank approach |
