On a Modification to the Harris Corner Detector
Niels Chr. Overgaard · Malmö University Publications (Malmö University) · 2003
This year, it is 15 years ago C. Harris and M. Stephens [1] presented a corner detector which is widely used today. While the algorithm itself, (usually referred to as the Harris detector,) is well-known, there are some theoretical points which we feel have not been appreciated. This paper has two purposes. First we recall the theory behind the Harris detector. Then, as a result of the theoretical analysis, we are lead to suggest a modi cation to the Harris detector. This modi cation is achieved by replacing the response function used in [1, p.150](or Eq. (4) below) by a new response function which seems more natural from a mathematical point of view, and whose performance is (at least) just as good.
