opencv-有关内存释放的一些问题
花了一天调试采集视频内存泄露的问题，所有申请的内存仔细检查过都已经释放问题仍然得不到解决，所幸在论坛上找到这篇文章，原来是cvCloneImage惹的祸！大神总结的很好，直接转载了： OpenCV中的内存泄露问题（cvLoadImage，cvCloneImage） 在做项目的过程中，使用OpenCV经常会出现一些内存泄露问题，自己编写的程序出现问题还情有可原，但若是库函数调用和
OpenCV: 使用C和C++开发到底哪个好？
C和C++都可以用来开发OPENCV，尽管OPENCV的源码是用C写的，但应用起来实际区别不大。我们看看老外的讨论。 菜鸟提问: 现在我正在使用OpenCV API（C++）开发一些应用程序。此应用程序使用视频进行处理。在电脑上，一切工作都很快。今天我决定把这个应用程序移植到Android上（用摄像头作为视频输入）。幸运的是，有了Android的opencv，所以我只是在示例Android应...
