CornerDetector:

-------------------------------------------------------------------------------
   Corner detector.
   n is the dimension of the region. thresh is the eigenvalue
   threshold.
   The corner output is [row start, row end, col start col end]
-------------------------------------------------------------------------------
   Form:
                 CornerDetector;
   [iC, coord] = CornerDetector( dX, dY, n )
   [iC, coord] = CornerDetector( dX, dY, n, thresh )
