前言: 最近想看看矢量中值滤波(Vector median filter, VMF)在GRB图像上的滤波效果,意外的是找了一大圈却发现网上没有现成的code,所以通过matab亲自实现了一个,需要学习的朋友可以拿过去用.本文的核心是VMF的matlab实现,最后通过在RGB图像上应用举例说明. VMF的数学表达: 含有N个矢量的集合{C1,C2,...CN},它的VMF结果如下所示: 其中,CVM1表示距离所有其他向量的距离和最小的那个向量.而距离可以自己定义,常用的欧氏距离,曼哈顿距离等等.…

四年前第一次看到<100+ Times FasterWeighted Median Filter (WMF)>一文时,因为他附带了源代码,而且还是CVPR论文,因此,当时也对代码进行了一定的整理和解读,但是当时觉得这个算法虽然对原始速度有不少的提高,但是还是比较慢.因此,没有怎么在意,这几天有几位朋友又提到这篇文章,于是把当时的代码和论文又仔细的研读了一番,对论文的思想和其中的实现也有了一些新的新的,再次做个总结和分享. 这篇文章的官网地址是:http://www.cse.cuhk.edu.h…

基于两步法的网格去噪算法顾名思义包含两个步骤:首先对网格表面的法向进行滤波,得到调整后的网格法向信息,然后根据调整后的法向更新顶点坐标位置,下面介绍三篇该类型的文章. [Sun et al. 2007]文章首先介绍了当前法向滤波方法以及顶点坐标更新方法,然后提出自己的法向滤波方法和顶点坐标更新方法. 法向滤波方法: 1.均值滤波(mean filter):ni’ = normalize(Σj∈N(i) Aj·nj / Σj∈N(i) Aj),均值滤波会破坏网格的细节特征. 2.中值滤波(medi…

今天看前辈博客的时候看到一种新的基于RGB颜色空间的image contrast enhance filter 流浪的鱼link: http://blog.csdn.net/jia20003/article/details/7385160#comments 算法的实现还是非常easy的. 左边的均是原图.右边的是增强后的图片,只是感觉RGB空间的算法都还是又色相转移的问题...这样的算法的效果没有HSV的效果好-说死点.这样的做法就是不正确的.... 一下參数均使用 对照度1.5 亮度 1 即对…
