摘要:

通过对图像的相似块做处理从而达到去噪目的,是当前较为新颖的去噪方法,在对国内外利用相似块去噪文献进行理解和分析的基础上,回顾相似块去噪研究的发展,阐明相似块去噪的原理,并总结了相似块去噪的各种方法。最终基于对相似块去噪方法的分析,提出了对其研究方法的展望。

关键词: 图像去噪, 非局部平均, 相似块, 小波去噪, 低秩逼近

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.

Key words: image denoising;non-local mean;similar patch;wavelet denoising;low-rank approach
