| Abstract(in English) | Various grouping principles have been applied to explain perceptual organization. To study how a smooth curve is processed in visual system, observers were presented with arrays of band-pass elements, and detection performance of an undulating path among randomly oriented distractors was measured as a function of the number of path elements and the orientation differences between adjacent path elements. It was found that the performance was better when the number of path elements was large or the orientation differences were small and constant. Based on the results, we propose a model that groups the path elements to be perceived as a contour, local orientation differences are detected by curvature channels and the output of these channels are globally pooled into the contour detectors with lateral inhibition, which signal if the threshold of more than two detectors are exceeded. |
