Description

If I have iterator on non-continious matrix i can't use '!=' operator to check that end is reached:

cv::Mat m(100, 100, cv::DataType<uchar>);
cv::Rect r(10, 10, 10, 10);

cv::Mat roi = m(roi);

for (cv::MatIterator_<uchar> it = roi.begin<uchar>(); it != roi.end<uchar>(); ++it)
{
// do something...
}

std::cout << "This is never been printed...";

My fix in attached file.
