Description

In GoodFeaturesToTrackDetector_GPU::operator() corners are (1) first found by computing locations with minimal eigenvalues and then (2) filtered according to a cell grid to force a minimal distance between feature points.

Step (2) is only executed if the 'minDistance' parameter is >= 1.

A uniform-colored image would cause no corners to be found. If step (2) is executed when no corners were found, this function fails (debug assertion is triggered) when executing the line:

Mat tmpMat(1, total, CV_32FC2, (void*)&tmp[0]);
