无法处理cvExtractSURF

Question

我正在尝试创建一个Android应用程序，它使用JavaCV通过其SURF功能匹配图像。

我正在尝试首先从Assets文件夹加载图像，为其提取SURF功能并将其保存在数据库中。在执行cvExtractSURF函数之前，代码似乎正常工作。实际上，我不确定它是否会被执行。模拟器/调试器开始思考，几分钟后，Eclipse说它已断开连接。真实设备上的同样问题：只是转到Home并且代码永远不会被执行。没有错误记录到Logcat，似乎没有异常抛出，没有.... 以下是发生这种情况的代码。

我搜索了类似的问题，但我似乎找不到任何问题。

忘了添加我正在使用OpenCV 2.3.1（由于新JavaCV的一些问题），2012年3月29日的JavaCV，Eclipse Indigo，Windows 7 32位。

我仍然是Android开发的新手，所以一点点的帮助将不胜感激。
