We propose an algorithm to recognize faces illuminated by arbitrarily placed, multiple light sources. The algorithm does not need to know the number of light sources and works extr...
Measuring a bidirectional reflectance distribution function (BRDF) requires long time because a target object must be illuminated from all incident angles and the reflected light...
We present techniques which create a consistent illumination between real and virtual objects inside an application specific optical see-through display: the Virtual Showcase. We ...
Novel similarity measures for object recognition and image matching are proposed, which are inherently robust against occlusion, clutter, and nonlinear illumination changes. They c...
Abstract: This paper surveys global illumination algorithms for environments including participating media and accounting for multiple scattering. The objective of this survey is t...
