Reconstruction of Subjective Surfaces from Occlusion Cues
In the Kanizsa figure, an illusory central area and its contours are perceived. Replacing the pacman inducers with other shapes can significantly influence this effect. Psychophysical studies indicate that the determination of depth is a task that our visual system constantly conducts. We hypothesized that the illusion is due to the modification of the image according to the higher level depth ...

E-mail address: [email protected] (Q. Li). To bring computer vision closer to human vision, we attempt to enable computer to understand the occlusion relationship in an image. In this paper, we propose five low dimensional...
متن کاملMonocular Depth Ordering using Perceptual Occlusion Cues
In this paper we propose a method to estimate a global depth order between the objects of a scene using information from a single image coming from an uncalibrated camera. The method we present stems from early vision cues such as occlusion and convexity and uses them to infer both a local and a global depth order. Monocular occlusion cues, namely, T-junctions and convexities, contain informati...
متن کاملDetecting natural occlusion boundaries using local cues.
Occlusion boundaries and junctions provide important cues for inferring three-dimensional scene organization from two-dimensional images. Although several investigators in machine vision have developed algorithms for detecting occlusions and other edges in natural images, relatively few psychophysics or neurophysiology studies have investigated what features are used by the visual system to det...
متن کاملDetection of Occluding Contours and Occlusion by Active Binocular Stereo
|We propose a reliable method to detect occluding contours and occlusion by active binocular stereo with an occluding contour model that describes the correspondence between the contour of curved objects and its projected image. Applying the image ow generated by moving one camera to the model, we can restrict possible matched points seen by the other camera. We detect occluding contours by tti...
