Mask-Oriented Grouping Operations in a Contour-Based Approach

Abstract

The goal of our investigation is a precise formulation of the Gestalt laws collinearity, curvilinearity, and proximity. Statistical results of hand labeled groupings are used to derive masks for the three different grouping operations, so called areas of "perceptual attentivness". These masks are applied to real images. Scaling according to the length of the individual contour segments assures a different size of the grouping and significantly reduces the complexity of grouping processes. 1 Introduction The perception of structure is relevant for our daily life. Apart from recognition of familiar objects humans have the ability for imposing structure to other parts of a scene as well. Witkin and Tenenbaum describe this mechanisms in [1]. They postulate, that a scene with regular structures implies some underlying causal relation. Any appearance of spatiotemporal coherence or regularity is unlikely to arise by chance. They named it the "principle of non-accidentalness". Allready in the...
