An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book",some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

PDF 1 Effects of background and contour luminance on the hue and brightness - 36 brightness of the interior region with increasing luminance of the inner contour 37 generating an assimilative filling-in for the hue judgments but a contrast effect for 38 the brightness judgments. Control analyses showed negligible effects for the 39 order of the luminance of the background or inner contour on the judgments. An

Contour effects on a brightness paradox - ScienceDirect - A contrast phenomenon in the form of a brightness paradox in the perception of certain luminance gradients in space has been investigated. In this study the influence on the paradox of demarcating the inducing from the induced fields by dark contours was measured. A "constant-sum" estimation method was used

PDF Subjective contours independent of subjective brightness - of subjective contours and subjective brightness effects. In one view, subjective contours are illusory brightness gradients generated from grouped local brightness effects. In another view, subjective contours are the edges of subjective forms created on the basis of gestalt factors; subjective brightness is a secondary consequence of form

PDF Central factors contributing to para-contrast modulation of contour and - Following up on a prior study of contour and brightness processing in visual masking ~Breitmeyer et al., 2006!,we investigated the effects of a binocular and dichoptic para-contrast masking on the visibility of the contour and brightness of a target presented to the other eye. Combined, the results support the contributions of several cortical

A paradox in the perception of luminance gradients. II - This brightness paradox was studied in a series of experiments using a magnitude estimation method. The main results were that both the changing sign of the second derivative of the luminance function (Mach's hypothesis) and the higher or lower luminance of an adjacent area (McDougall's drainage theory) are critical conditions for the

For details about how model outputs were scaled to match the magnitude estimations, see Section 4.2. 2.3 Contour Effects on Binocular Brightness The ganzfeld results suggest that, in the absence of contours, brightness signals summate

Perception - Context effects | Britannica - One of the simplest instance of relational (or context) effects in perception is that of brightness contrast. Thus, the apparent brightness of a stimulus depends not only on its own luminance but also on that of the surrounding stimulation. The same gray square looks whiter against a dark background and blacker when placed in a bright surround. Similarly, a white or gray patch will take on an

Frontiers | A Neurocomputational account of the role of contour - A new filling-in model is proposed in order to account for challenging brightness illusions, where inducing background elements are spatially separated from the gray target such as dungeon, cube and grating illusions, bullseye display and ring patterns. This model implements the simple idea that neural response to low-contrast contour is enhanced (facilitated) by the presence of collinear or

Neural dynamics of binocular brightness perception - Contour effects on binocular brightnessThe Ganzfeld results suggest that, in the absence of contours, brightness signals summate. Leibowitz and Walker (1956) demonstrated that as the size of two square fields, viewed dichoptically, increases from 15 to 60 min in width, brightness summation (measured by a brightness-matching procedure) triples

- In this study the influence on the paradox of demarcating the inducing from the induced fields by dark contours was measured. A “constant-sum” estimation method was used. The result was a decrease in brightness paradox when contours were introduced between inducing and induced fields

NEURAL DYNAMICS OF BINOCULAR BRIGHTNESS PERCEPTION Stephen - The effect is paradoxical since, despite the increased total stimulation on both retinas, the perceived binocular brightness is decreased. The effect has been replicated experimentally several times (DeSilva and Bartley, 1930; Fry and Bartley, 1933), with some focusing primarily on brightness averaging or summation (, Ivanoff, 1947)

Ehrenstein illusion - Wikipedia - The brightness effect disappears when the line segments are joint with a circular disk. This fits under the characteristics of an optical illusion, as there are no physical origins to the asymmetrical perceptual sensations we perceive. A similar effect of illusory contour is seen in figures such as the Kanizsa triangle
