NonlocalMeansFilter NonlocalMeansFilter[image,r] 通过比较范围为 r 的邻域和它的附近邻域,对 image 应用非局域均值滤波器. NonlocalMeansFilter[image,r,ns] 在比较邻域时,假定附加噪声功率值 ns. NonlocalMeansFilter[image,r,ns,w] 在范围为 w 的窗中比较邻域....
The proposed method is based on non-local means (NLM). NLM methods have been applied successfully in various image denoising applications. In the single-frame NLM method, each output pixel is formed as a weighted sum of the center pixels of neighboring patches, within a given search window. ...

SINGLE-IMAGE DERAINING USING AN ADAPTIVE NONLOCAL MEANS FILTER论文分析(以公式分析为主导) 文章摘要(基于自适应非局部均值滤波器的单图像去雨): 提出了一种适用于单幅图像的自适应雨条纹去除算法。我们观察到一个典型的雨带有一个垂直方向的椭圆形拉长。因此,我们首先通过分析椭圆核在每个像素位置的旋转角度和长宽...
Non-Local Means顾名思义,这是一种非局部平均算法。何为局部平均滤波算法呢?那是在一个目标像素周围区域平滑取均值的方法,所以非局部均值滤波就意味着它使用图像中的所有像素,这些像素根据某种相似度进行加权平均。滤波后图像清晰度高,而且不丢失细节。
Image Deblocking with Adaptive Non-local Means Filter Common image compression standards such as JPEG and MPEG can lead to blocking artifacts which causes serious image degradation.In this paper,a non-local me... S Liu,C Wang - 《Journal of Shanghai Jiaotong University》 被引量: 2发表: 2013...
因此我们需要一个Non-Local连接,而non-local也有理由表现得更好,就好比Non-Local means方法比local filter方法去噪更强,dense crf比普通的crf更强一样。 3 怎么实现 首先要说明的是,non-local可以是只在图像空间上的non-local,也可以是不同时间帧上的non-local,甚至是两者的融合,不过理解起来都是一样的。 上面...
The MDNLM combines the feature of preserving edge information by the nonlocal means filter with the capacity of capturing directional image information by the directional filter bank, which can effectively represent the intrinsic geometric structure of images. The MDNLM is a multiscale, ...
