Subjective contours and apparent depth.
Schumann (1904) investigated the physical parameters which affect the perception of contour. He reported that for a contour to be perceived the prerequisite was some relatively abrupt local change in brightness or color. In the course of these investigations, however, he noted that under certain favorable conditions contours could be made to appear in areas of the visual field where the physica...
متن کاملSubjective contours and apparent depth: a direct test.
however, explains such secondary effects associated with subjective contours as changes in brightness or in apparent depth. In contradistinction to the physiological explanations are a number of hypotheses that are primarily cognitive in nature. Kanizsa (1976) maintains that illusory contours are merely an unusually strong example of the Gestalt principle of closure. Other theorists suggest, ra...
متن کاملDepth from subjective color and apparent motion
We report that color and depth, as well as form, are recovered in tandem with seeing motion. The stimulus, consisting of multiple frames, was designed to keep all aspects, except color, of the binocular images identical. In still view, rivalry occurs due to the unmatched color of some corresponding image elements in the two eyes. When frames--created by translating color assignments and nothing...
متن کاملShape Encoding and Subjective Contours
Ullman proposes that subjective contc,.us consist of two circles which meet smoothly and which arc tangential to the contrast boundaries from which they originate. The foim of the solution derives from a number of premises, one of which Ullman calls “the locality hypothesis”. ‘Ihis is “based in part on cxpcrimcntal obscrvntions, and partly on a theoretical consideration” ([I 51 ~2). ‘I’hc “cxpc...
متن کاملTransparency: relation to depth, subjective contours, luminance, and neon color spreading.
The perception of transparency is highly dependent on luminance and perceived depth. An image region is seen as transparent if it is of intermediate luminance relative to adjacent image regions, and if it is perceived in front of another region and has a boundary which provides information that an object is visible through this region. Yet, transparency is not just the passive end-product of th...
