摘要：

An improved version of block-matching with 3D transform domain collaborative filtering (BM3D) with choosing the matching distance adaptively is proposed in this paper. We use SSIM, gradient and noise level to describe the distinct between the reference blocks and its corresponding patches. Meanwhile, the dissimilar blocks are removed from the group matrix in the framework of BM3D. Especially, it makes up the disadvantage of BM3D in the condition of the image with high noise level. Experimentally, the proposed method demonstrates its effective capacity to denoise, improves the peak signal-to-noise ratio of the image, and keeps better visual result in edges information reservation as well.
