Illusory gloss on Lambertian surfaces.
It has recently been shown that an increase of the relief height of a glossy surface positively correlates with the perceived level of gloss (Y.-H. Ho, M. S. Landy, & L. T. Maloney, 2008). In the study presented here we investigated whether this relation could be explained by the finding that glossiness perception correlates with the skewness of the luminance histogram (I. Motoyoshi, S. Nishida...
متن کاملRendering Caustics on Non-Lambertian Surfaces
This paper presents a new technique for rendering caustics on non Lambertian surfaces The method is based on an extension of the photon map which removes previous restrictions limiting the usage to Lambertian surfaces We add information about the incoming direction to the photons and this allows us to combine the photon map with arbitrary re ectance functions Furthermore we introduce ba lancing...
متن کاملProblems of Perceiving Gloss on Complex Surfaces
Over the past 20 years, there have been many studies looking at how highlight disparity affects an observer's perception of glossiness. Most of these studies have used relatively smooth surfaces, and simple lighting models. We are using surfaces which are rougher and more naturalistic than those used before, using a rendering method which takes into account physically accurate properties of lig...
متن کاملPerceiving Gloss in Surfaces and Images
Color Appearance Models are successfully used to model the color perception differences seen when the same stimuli are presented on different media, e.g. hard copy or a self-luminous display. It is currently unknown if the similar effects are present in gloss perception and if there is need for Gloss Appearance Models. Gloss communication, and the higher level material appearance communication ...
متن کاملDepth perception of illusory surfaces
The perception of an illusory surface, a subjectively perceived surface that is not given in the image, is one of the most intriguing phenomena in vision. It strongly influences the perception of some fundamental properties, namely, depth, lightness and contours. Recently, we suggested (1) that the context-sensitive mechanism of depth computation plays a key role in creating the illusion, (2) t...
