In this paper we extend the reuse of paths to the shot from a moving light source. In the classical algorithm new paths have to be cast from each new position of a light source. W...
We define the antiumbra and the antipenumbra of a convex area light source shining through a sequence of convex areal holes in three dimensions. The antiumbra is the volume from w...
Interactive visualization of complex, real-world light sources has so far not been feasible. In this paper, we present an hardware accelerated direct lighting algorithm based on a...

This paper proposes a hardware-based line feature enhancement approach that uses a palmprint acquisition device fitted with a time-sharing light source. When capturing images, two ...
This paper presents an approach for creating realistic shadows of objects composited into a novel background. Existing techniques either do not deal with the shadows or require th...
This paper presents a novel image-based approach to render plausible soft shadows for complex dynamic scenes with rectangular light sources. The algorithm's performance is mo...
Abstract. When creating a digital composite of two people, it is difficult to exactly match the lighting conditions under which each individual was originally photographed. In many...
We describe a new, analytic approximation to the airlight integral from scattering media whose density is modeled as a sum of Gaussians. The approximation supports real-time rende...

— In this paper, we propose an original approach to control camera position and/or lighting conditions in an environment using image gradient information. Our goal is to ensure a...
Even though shadows are important for photometric consistency in Mixed Reality (MR) [1]. When human cannot perceive the inconsistency of artificial shadows which are not physicall...
