On Significant Crisp Representatives of Fuzzy Regions in Colour Images

Abstract

Abstract — In this paper we propose a technique to obtain a set of crisp representatives of an imprecise region in color images. In our approach, we start by obtaining a fuzzy model of the region by employing a fuzzy region growing procedure. The set of crisp representatives is obtained from that model as the set of α-cuts corresponding to maximal variations of homogeneity. Several experiments and a comparison with both crisp and fuzzy techniques are provided, showing the suitability of the proposal against other approaches
