2004 (English)In: Proceedings of Pattern Recognition, 26th DAGM Symposium / [ed] Carl Edward Rasmussen, Heinrich H. Bülthoff, Bernhard Schölkopf and Martin A. Giese, SpringerLink , 2004, Vol. 3175, 103-110 p.Conference paper (Refereed)
In this paper we address one of the standard problems of image processing and computer vision: The detection of points of interest (POI). We propose two new approaches for improving the detection results. First, we define an energy tensor which can be considered as a phase invariant extension of the structure tensor. Second, we use the channel representation for robustly clustering the POI information from the first step resulting in sub-pixel accuracy for the localisation of POI. We compare our method to several related approaches on a theoretical level and show a brief experimental comparison to the Harris detector.
