Non-Bayesian Contour Synthesis
Recent research has witnessed an explosive increase in models that treat percepts as optimal probabilistic inference. The ubiquity of partial camouflage and occlusion in natural scenes, and the demonstrated capacity of the visual system to synthesize coherent contours and surfaces from fragmented image data, has inspired numerous attempts to model visual interpolation processes as rational infe...
متن کاملBayesian contour integration.
The process by which the human visual system parses an image into contours, surfaces, and objects--perceptual grouping--has proven difficult to capture in a rigorous and general theory. A natural candidate for such a theory is Bayesian probability theory, which provides optimal interpretations of data under conditions of uncertainty. But the fit of Bayesian theory to human grouping judgments ha...
متن کاملA Bayesian Contour Measure for Image Segmentation
The Bayesian approach to image segmentation defines a penalty function of image partitions such that the function’s minima correspond to perceptually salient segments. We extend previous approaches following this framework by requiring that our image model sharply decrease in probability as a segment’s boundary is perturbed from its true position. Instead of making segment boundaries prefer ima...
متن کاملBayesian Synthesis
Bayesian model averaging enables one to combine the disparate predictions of a number of models in a coherent fashion, leading to superior predictive performance. The improvement in performance arises from averaging models that make different predictions. In this work, we tap into perhaps the biggest driver of different predictions—different analysts—in order to gain the full benefits of model ...
متن کاملMotion-Based Mechanisms of Illusory Contour Synthesis
Neurophysiological studies and computational models of illusory contour formation have focused on contour orientation as the underlying determinant of illusory contour shape in both static and moving displays. Here, we report a class of motion-induced illusory contours that demonstrate the existence of novel mechanisms of illusory contour synthesis. In a series of experiments, we show that the ...
