Hi,

If you try to use this code:

Mat m = imRead("D:\\pic.jpg",1);
GpuMat gm;
gm.upload(m);
GpuMat roi(gm, Rect(0,0,gm.rows-1, gm.cols-1);

An error will raises !

cv::Rect has next constructor:

Rect(int x, int y, int width, int height);

Correct code (swap last two parameters):

GpuMat roi(gm, Rect(0, 0, gm.cols-1, gm.rows-1);
