NL-Means和BM3D可以说是目前效果最好的去噪算法,其中BM3D甚至宣称它可以得到迄今为止最高的PSNR。从最终的结果也可以看出来,BM3D的效果确实要好于NL-Means,噪声更少,能够更好地恢复出图像的细节。在效果这一点上BM3D胜。无愧于State-of-the-art这一称号。当然,这里进行测试的样本比较少,可能还不足以完全说明问题。
简介:非局部均值滤波算法(NL-means)。非局部均值滤波算法最早于2005年由Buades等人发表在CVPR上,论文原文:A non-local algorithm for image denoising,还有一篇2011年的论文:Non-Local Means Denoising。之后还会继续介绍DCT(离散余弦变换滤波)、TV(全变分滤波)、BM3D(3维块匹配滤波)等算法。 上一篇文章介绍了均值滤波...

A non-local algorithm for image denoising (2005) Antoni Buades et .al. 这个是NL - means的文章,首先,作者对图像去噪算法做了一个概括,说他们的出发点都是这个basic remark : denoising is achieved by averaging. 而这个average具体的操作可以有不同,可以是locally的,可以是anisotropic filtering,可以是neighbor...
