帧间差分法是一种通过对视频图像序列中相邻两帧作差分运算来获得运动目标轮廓的方法，它可以很好地适用于存在多个运动目标和摄像机移动的情况。当监控场景中出现异常物体运动时，帧与帧之间会出现较为明显的差别，两帧相减，得到两帧图像亮度差的绝对值，判断它是否大于阈值来分析视频或图像序列的运动特性，确定图像序列中有无物体运动。图像序列逐帧的差分，相当于对图像序列进行了时域下的高通滤波。实例中有对应avi文件(Inter-frame difference method is a method that obtains the contour of moving object by differential operation of two adjacent frames in video image sequence. It can be well applied to the situation where there are multiple moving objects and camera moving. When abnormal object motion occurs in the monitoring scene, there will be obvious difference between the frame and the frame. By subtracting the two frames, the absolute value of the brightness difference between the two frames can be obtained. The motion characteristics of video or image sequence can be analyzed by judging whether it is larger than the threshold value, and whether there is object motion in the image sequence can be determined. The frame-by-frame difference of image sequence is equivalent to high-pass filtering of image sequence in time domain. There are corresponding avi files in the instance)

这两天在网上看到一张让人涨姿势的图片，图片中展示的是贪吃蛇游戏， 估计大部分人都玩过。但如果仅仅是贪吃蛇游戏，那么它就没有什么让人涨姿势的地方了。 问题的关键在于，图片中的贪吃蛇真的很贪吃XD，它把矩形中出现的食物吃了个遍， 然后华丽丽地把整个矩形填满，真心是看得赏心悦目。作为一个CSer， 第一个想到的是，这东西是写程序实现的(因为，一般人干不出这事。 果断是要让程序来干的)第二个想到的是，写程序该如何实现，该用什么算法？ 既然开始想了，就开始做。因为Talk is cheap，要show me the code才行。
