 检测视频中镜头切换的关键帧 检测镜头切换的基本思想是：对比视频中前后两帧灰度差，若两帧差值超过阈值，则说明视频中的镜头转换了，并把这一帧作为关键帧保存下来。 定义相应的指针和结构 初始化指针和结构 计算视频中前后两帧的灰度差 将两帧的灰度差值与阈值比较，超过阈值，则将其判定为关键帧保存  其中阈值大小根据视频的情况进行调整

实验中发现opencv的cvCaptureFromCAM 使用的是vfw,采用消息机制,速度较慢,测试发现fps只有 9-12左右,太慢了. 发现经过使用directshow后速度提升到60帧/s.在opencv group上了解到这是一个普遍问题,也许有人做过转换,却没有完整的例子与代码.在此贴出.对希望提高opencv视频分析速度的有所帮助-Opencv experiment found that the cvCaptureFromCAM using vfw, the use of information mechanism to slow fps test found that only about 9-12, too slow. Discovered through the use of DirectShow velocity to 60/s. In opencv group understanding that this is a common problem, perhaps someone has done the conversion, but no complete examples and code.此贴out in. opencv want to improve the speed of video analysis help
