基于混合高斯的运动目标检测程序已经相应的文章！非常值得借鉴！(Gaussian mixture-based moving object detection procedures have been the appropriate article! Well worth learning!)

说明：  该文件是MATLAB图形图象处理程序，对于学习MATLAB和做图形图象处理的哥们非常有用，次程序作为共享文件，请下载后勿作为商业用途，(MATLAB graphics image processing procedures, learning MATLAB graphics and image processing to do the Miners very useful meeting procedures as sharing files, please download not used for commercial purposes, thank you)

说明：  图片的平滑锐化以及二值化。。。。。。。。。。。。。。。(Sharpening and smoothing the image binarization)

： 对一种基于图像几何重心的特征点提取算法进行了改进 改进后的算法可以提取任何边缘线上凹凸处的特征点 其基本 思想是，首先提取图像的边缘轮廓线，计算封闭边缘线和非封闭边缘线的几何重心 然后以重心为极点，对边缘点极坐标化，形成 幅角-极径曲线，在该曲线上寻找局部极大极小值点 最后根据局部非极大（小）抑制原则对极大（小）值点进行取舍获得特征点 模 拟结果表明算法计算简单 稳定性好 该方法提取的特征点能准确地反映目标的形状，对目标的识别 跟踪以及三维表面重建等都 具有重要的价值(This paper modifiesakindoffeatureextractingalgorithmbasedonimageedge.First， imageedgeoutlineisextracted.
