二、Non-Local Neural Network 2.1 回顾Non local means Non local means filter,即非局部均值滤波算法,是图像去噪领域一个非常有名的算法。我读研一时有个大四的学妹在做毕设,问我说她想找个传统去噪算法作为她跑的DL代码的对比方法,我就给她推荐了NLM(当时我也没听过几个传统去噪算法哈哈,所以应该算是...
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...

而更大的感受野对于视频图像中的场景理解,跟踪,语音识别等时序问题都是必要的。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...
