| 摘 要： | 图像去噪作为一种重要的预处理手段,一直以来都是图像处理和计算机视觉领域的研究热点。去噪算法的难点在于去除噪声的同时尽可能保持原始信息的完整性。本文主要研究TV,BLS-GSM,NLM以及BM3D四种经典去噪算法的基本原理,并用模拟数据验证分析四种算法在图像去噪中的性能,实验证明,四种算法均能在保留图像细节的前提下很好的去除噪声,其中,BM3D算法在保证去噪质量的同时效率最高。

| Abstract: | Image denoising is an important method of preprocessing, it is one of the forelands in the field of Computer Graphic and Computer Vision. The difficulties of denoising algorithm is not only to remove the noise, but also to keep the original information as well. This paper mainly research on the principle of four classic denoising algorithm, which are TV, BLS - GSM, NLM and BM3D, we use simulate data for image denoising to analysis the performance of the four algorithms, experiments demonstrate that the four algorithms can remove the noise, the BM3D algorithm not only have high quality of denosing, but also have the highest efficiency at the same time. |

| Keywords: | image denoising total variation gaussian scale mixtures non-local means block-matching and 3D filtering |
