一个处理hough变换的源码，希望大家能有点用，不过是一个matlab的源码，一会再传一个C的-Hough transform a deal with source code, hope that we can use a little bit, but is a matlab source code, one would send a C of

对视频图像序列使用卡尔曼滤波器生成背景。卡尔曼滤波是利用其的记忆特性，对一定时间长度的视频图像信息进行加权平均从而获得与实际背景图像近似的初始背景，同时达到滤除颗粒噪声、消除摄像机抖动的目的。

基于图像直方图均衡化的公式来编程。像素一共分为256个灰度阶，每个灰度阶用数组的一个相应nk[？]来储存它的个数，然后计算tk[？]。-Based on image histogram equalization formula programming. Pixel is divided into a total of 256 gray-scale bands, each of the gray band with a corresponding array nk [? ] To store the number of it, and then calculating tk [? ].
