用于水下视频监控系统的背景查分算法，用matlab编写-Underwater video monitoring system for the background check sub-algorithm, matlab write

背景差分检测代码，利用背景差分方法检测运动目标，可以实现-The background differential detection code, using background subtraction method to detect moving targets can be achieved

最简单的频间差分，读取avi，分别显示背景、前景和查分后的图像。XP、opencv2.4.3环境运行。-The frequency difference between the easiest to read avi, respectively, show the background, foreground and check points after images.

输入图片序列，实现背景差分，换成自己的图片可直接运行-input the imgs to implementate background difference

开始选择一个与之作为初始估计值，按照某种规则更新估计值，直至满足给定条件，此种方法迭代迅速收敛，每次迭代结果优于上次迭代(By choosing one as the initial estimate and updating the estimate according to some rule until the given condition is satisfied, the method converges quickly, and the result of each iterati
