Grounding the figure: surface attachment influences figure-ground organization.
We investigated whether the lower region effect on figure-ground organization (Vecera, Vogel, and Woodman, 2002) would generalize to contextual depth planes in vertical orientations, as is predicted by a theoretical analysis based on the ecological statistics of edges arising from objects that are attached to surfaces of support. Observers viewed left/right ambiguous figure-ground displays that...
متن کاملDepth adjacency and the Ponzo illusion
The effect of depth displacement of test bars from the induction wedge of the Ponzo illusion was investigated in two experiments. Either two wedges of opposite orientation were presented simultaneously, one at a near and the other at a far distance, or only one wedge was presented at either the near or the far distance. The test bars were stereoscopically either in the plane of the wedge or dis...
متن کاملA neural model of figure-ground organization.
Psychophysical studies suggest that figure-ground organization is a largely autonomous process that guides--and thus precedes--allocation of attention and object recognition. The discovery of border-ownership representation in single neurons of early visual cortex has confirmed this view. Recent theoretical studies have demonstrated that border-ownership assignment can be modeled as a process o...
متن کاملFigure-Ground Organization using 3D Symmetry
We present a novel approach to object localization using mirror symmetry as a general purpose and biologically motivated prior. 3D symmetry leads to good segmentation because (i) almost all objects exhibit symmetry, and (ii) configurations of objects are not likely to be symmetric unless they share some additional relationship. Furthermore, psychophysical evidence suggests that the human vision...
متن کاملModel Theory of Figure Ground Location
In this paper a model theory for figure ground locations is proposed. Figure ground locations are n-tuples of predicates about relations between regional individuals and a set of regional individuals forming a regional partition of the plane. This language is based on the RCC-theory which is extended by a number of definitions and axioms constraining the models to the set of regular closed sets...
