error:

OpenCV Error: Assertion failed (0 <= roi.x && 0 <= roi.width && roi.x + roi.width <= m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows) in cv::Mat::Mat, file C:\build\master_winpack-build-win64-vc14\opencv\modules\core\src\matrix.cpp, line 522

问题原因：

You are probably working outside of the image dimensions. Does any of the values you pass to the cvSetImageROI function lay outside the image boudaries?
