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 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 کاملConjoint measurement of gloss and surface texture.
The image of a material's surface varies not only with viewing and illumination conditions, but also with the material's surface properties, including its 3-D texture and specularity. Previous studies on the visual perception of surface material have typically focused on single material properties, ignoring possible interactions. In this study, we used a conjoint-measurement design to determine...
متن کاملInspection of specular and painted surfaces with centralized fusion techniques
This contribution presents new strategies to inspect specular and painted surfaces. Structures on such surfaces are normally only visible, if patterns of the environment are reflected in them. Thus, conventional approaches only yield a little information gain from a single measurement. In our approach, different intensity patterns are systematically generated in the environment of the surface s...
