我想运行出gtihub的这个程序https://github.com/JaimeIvanCervantes/Tracking 该程序是基于qt和opencv的识别运动的目标
该代码使用的版本好像是opencv2，但是我使用的版本是opencv4.3。在改进代码之后编译通过了可以运行出界面来。但是当我加载视频之后程序自动退出了，应用程序输出报错。如果注释掉medianBlur这一行那么就会对erode报错，请问这是为什么呢？
// Threshold and morphology operations
cv::threshold(foregroundFrame,foregroundFrame,130,255,cv::THRESH_BINARY);
cv::medianBlur(foregroundFrame,foregroundFrame,5);
cv::erode(foregroundFrame,foregroundFrame,cv::Mat());
cv::dilate(foregroundFrame,foregroundFrame,cv::Mat());
Qt报错
