[Video Capture] USB摄像头视频读取实时处理

Description:

VFW效率比较高的USB摄像头视频读取＋实时处理，
FrameCallBack的效率高过拷贝到剪贴板 再读取的操作

里面还有YUY2视频解码的处理，都替你弄好了！

overlay 显示模式 替代 preview方式  ， 大大减小CPU的负担。

效率虽然比不上DirectShow ，但是也可以了

将亮度曲线集成到 preview 窗口，放个手指在摄像头前面晃晃试一试。COOL 吧!!!

刚刚加入 slider ，尚未加入消息操作 。


hujin@suda.edu.cn 如果觉得好，email给我一点好的源码！

[DirextX] Directshow_Opencv

Description: 本例提供了使用directshow代替opencv的vfw 的源代码,与转化为iplimage格式的算法. 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。-Provided in this case the use of DirectShow to replace the VFW opencv source code, and translated into algorithms iplimage format. Opencv experiment found 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 to speed after 60/s.
