Hey everyone,
I just copied past the code from the Cascade classifier tutorial , And I always get this error
OpenCV Error: Assertion failed (0 <= roi.x && 0 <= roi.width && roi.x + roi.widt h <= 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

Any help please ?
