Description

The ORB keypoint detector seems to select keypoints outside of the specified region of interest (ROI). Note that the keypoints outside of the ROI are close to the boundary but still outside (see the dilation part in the attached test-case). I noticed this while migrating a project of mine from OpenCV 2.3.1 to OpenCV 2.4.0; the issue occurred only with the recent version, so I assume that I haven't done anything wrong here. I have attached a small test-case, a Makefile, and the example images required by the test-case.
