2015-07-01 12:10:13 -0600	asked a question	Access violation when using cv::sum() on ROI of a Matrix `cv::Mat mask(45, 45, CV_32F, 0); cv::Mat roi1(mask, cv::Rect(0, 0, 15, 15)); cv::Mat roi2(mask, cv::Rect(15, 0, 15, 15)); cv::sum(roi1); // no access violation cv::sum(roi2); // access violation` Why is there an access violation when trying to get the sum of `roi2`? It seems that it's clearly inside the boundaries of `mask`. Using Visual Studio 2010 and OpenCV 2.4.10
