A Theoretical Analysis of Illusory Contour Formation in Stereopsis
A theoretical analysis of how illusory contours are formed in untextured stereograms is presented. This analysis focuses on the role of contour junctions in initiating surface interpolation processes. More specifically, this theory asserts that the matching geometry of stereoscopic junctions that is, the pattern of matchable and unmatchable features present at the intersection of binocularly vi...
متن کاملIllusory-contour formation affected by luminance contrast polarity.
We report a new type of illusory contour (Illusory-O) whose formation is contingent upon the contrast polarity of its juxtaposed inducing elements being similar, i.e. both elements must either be positive or negative in contrast sign. To test the hypothesis that this contingency is primarily dictated by factors that determine amodal surface completion (occlusion) between the inducing elements w...
متن کاملWhen does illusory contour formation depend on contrast polarity?
Performance on a shape discrimination task was used to investigate when, and to what extent, illusory contour formation depends upon contrast polarity. It was found that shape discrimination performance was markedly worse when contrast polarity reversed within inducers, changing abruptly at the corners, than between inducers. This difference was most evident for stimulus durations from 80-320 m...
متن کاملThe Nature of Illusory Contour Computation
Neural correlates of illusory contour perception have been found in both the early and the higher visual areas. But the locus and the mechanism for its computation remain elusive. Psychophysical evidence provided in this issue of Neuron shows that perceptual contour completion is likely done in the early visual cortex in a cascade manner using horizontal connections.
متن کاملMultiple mechanisms of illusory contour perception.
A variety of mechanisms have been proposed to explain illusory contour formation. However, since prior studies have focused on a single mechanism, there is no clear consensus regarding contour formation mechanisms. Here we developed a novel vivid dynamic display we call the chomping pacman that allows measurement of minute differences in contour clarity. This illusion is shown to be more vivid ...
