Visual Attention Model in Figure-Ground Reversal Perception
In figure-ground reversal perception for ambiguous figures, figure-ground relationship reverses depending on the position and the range of our attention. Our attention also changes depending on figural features. We propose a neural network model that explains a dynamic process concerning figure-ground perception and visual attention. Our model consists of two mechanisms: (i) one determines figu...
متن کاملExpectation and satiation accounts of ambiguous figure-ground perception
An expectancy account of figure-ground shifts, promoted as an alternative to satiation theory, was tested. One-hundred and three subjects in six conditions (Experiment 1) were either informed or uninformed about 12 to 13 ambiguous figures, and had either unlimited time or 30 sec in which to respond. In two of the conditions, head and eye movements were restricted, and in one condition, incident...
متن کاملInhibitory competition in figure-ground perception: context and convexity.
Convexity has long been considered a potent cue as to which of two regions on opposite sides of an edge is the shaped figure. Experiment 1 shows that for a single edge, there is only a weak bias toward seeing the figure on the convex side. Experiments 1-3 show that the bias toward seeing the convex side as figure increases as the number of edges delimiting alternating convex and concave regions...
متن کاملEdge-region grouping in figure-ground organization and depth perception.
Edge-region grouping (ERG) is proposed as a unifying and previously unrecognized class of relational information that influences figure-ground organization and perceived depth across an edge. ERG occurs when the edge between two regions is differentially grouped with one region based on classic principles of similarity grouping. The ERG hypothesis predicts that the grouped side will tend to be ...
