我正在使用 opencv2.3.1 和 Visual Studio 2010
我正在尝试实现用于背景减法/前景提取的 FGD 算法。
我已经成功实现了 MOG 算法。然后我只是将函数和参数从 MOG 更改为 FGD。
该项目在visual studio上成功编译，但功能：cvShowImage("BG", bgModel->background); 它给出了以下错误：
hello_opencv_231.exe 中 0x000007feef085d09 处的未处理异常：0xC0000005：访问冲突写入位置 0xfffffffcc40b40e0。
我不知道这是什么......有什么想法吗？
谢谢你的帮助！
