1) nonlocal means filtering 非局部均值滤波1. In terms of characteristics of similarity of various structural primitives, a two-stage nonlocal means filtering is used for alleviating the impact of noise on structural similarity measures, and hence improve the despeckling performance. 提出了一种基于...
Non-local means filteringOptimization92C5560G3565K10Characterizing functional brain connectivity using resting functional magnetic resonance imaging (fMRI) is challenging due to the relatively small Blood-Oxygen-Level Dependent contrast and low signal-to-noise ratio. Denoising using surface-based Laplace-...
NL-Means的滤波过程可以用下面公式来表示: BM3D算法(Block-matching and 3D filtering) 该算法的思想跟NL-Means有点类似,也是在图像中寻找相似块的方法进行滤波,但是相对于NL-Means要复杂得多,理解了NL-Means有助于理解BM3D算法。BM3D算法总共有两大步骤,分为基础估计(Step1)和最终估计(Step2): 在这两大步中,分...
