The Persistence of Vision in Spatio-Temporal Illusory Contours formed by Dynamically-Changing LED Arrays
LED displays produce anomalous spatio-temporal (moving) illusory contours involving the apparent (perceived) shift in the position of physical stimuli and resulting in an apparent tilt of the displayed pattern. This illusion may be explained by a spatio-temporal grouping which is dependent on the persistence of vision associated with illusory contours. Empirical measurements corroborate existin...
متن کاملVisual constraints for the perception of quantitative depth from temporal interocular unmatched features
Previous research (Brooks & Gillam, 2006) has found that temporal interocular unmatched (IOUM) features generate a perception of subjective contours and can result in a perception of quantitative depth. In the present study we examine in detail the factors important for quantitative depth perception from IOUM features. In Experiments 1 and 2 observers were shown temporal IOUM features based on ...
متن کاملIllusory contours
Illusory contours are perceived in the absence of any real physical luminance gradients between inducers that are spatially discontinuous (Fig. 1a,b).1–3 It has been controversial whether the perception of these subjective contours arise from higher level cognitive mechanisms that depend on attention and serial search4–6 or from lower level parallel processing in the early automatic, preattenti...
متن کاملExtraction of Illusory Contours by Perceptual Grouping
The detection of arbitrary objects in images is still a major challenge in image processing. Many approaches rely on the robust extraction of contours. Object contours, however, are frequently occluded by other objects. How can one deal with this problem? One important source for inspirations in such diicult situations is the human visual system. There are several systems that describe the earl...
متن کاملCurvature coding in illusory contours
We have employed the shape frequency and shape-amplitude after-effects (SFAE and SAAE) to investigate: (i) whether the shapes of illusory and real curves are processed by the same or different mechanisms, and (ii) the carrier-tuning properties of illusory curvature mechanisms. The SFAE and SAAE are the phenomena in which adaptation to a sinusoidal-shaped contour results in a shift in, respectiv...
