基于BM3D图像去噪算法的参数研究

BM3D算法是目前最好的图像去噪算法之一,最近提出的很多更有效的去噪算法都是以BM3D算法作为对比基准。BM3D算法先通过块匹配生成三维矩阵,然后在三维变换域去噪,最后逆变换还原图片。通过对BM3D算法的深入研究,发现BM3D算法的性能与它的参数密切相关。针对BM3D算法的参数进行了实验统计,并对BM3D算法的参数设置进行了总结。实验不仅验证了BM3D算法在图像去噪方面取得了较好效果,而且为BM3D算法的参数设定提供了借鉴。

Parameters Study Based on BM3D Image Denoising AIgorithm

BM3D algorithm is one of the best image denoising algorithms,and a lot of more effective denoising algorithms proposed recently are compared with BM3 D algorithm.At first,BM3 D algorithm generate a three-dimensional matrix through block matching,then denoising at the three-dimensional transform domain,finally get the image through inverse transform.By means of studying BM3 D algorithm deeply,thia paper discover that its performance is closely related to the parameters.This paper make experiments and count the results for the BM3 D algorithm,and arrive at a conclusion of the BM3 D algorithm parameters.
