A Model of Salient Parts Extraction on the Cognition of Visual Patterns’ Shapes

Abstract

It is known that not all parts of the visual patterns are not equally perceived, but convex parts are perceived more saliently than concave parts (Subirana-Vilanova & Richards, 1996, etc.). However, it is not a trivial to determine where are the salient parts, because convex / concave parts become clear through the analysis of the whole pattern. This study proposes a simple model to extract perceptually salient parts on the shape cognition based on the model of figure-ground separation proposed previously by the author. The function of the model was confirmed by computer simulation.
