The fast identification of shadow regions due to area light sources is necessary for realistic rendering and for discontinuity meshing for global illumination. A new shadow-determ...
The appearance of a particular object depends on both the viewpoint from which it is observed and the light sources by which it is illuminated. If the appearance of two objects is...
Shadows are of great importance to computer graphics, especially for interactive animation due to the visual cues which they provide. Most research in the field of dynamic shadowi...
Finding the “best” viewing parameters for a scene is quite difficult but a very important problem. Fully automatic procedures seem to be impossible as the notion of “best...
This paper proposes an augmented reality system with correct representation of shading and shadow. To realize a seamless augmented reality system, we need to resolve some problems...
We present a new method for detecting rapid eye movements called a saccade without constraining the head, based on the fast, robust pupil detection technique [1][2]. The technique...
Photometric stereo relies on inverting the image formation process, and doing this accurately requires reasoning about the visibility of light sources with respect to each image po...
This paper presents a novel scheme for locating multiple light sources and estimating their intensities from a pair of stereo images of a sphere. No prior knowledge of the location...
We present a method for shape reconstruction from several images of a moving object. The reconstruction is dense (up to image resolution). The method assumes that the motion is kn...
In this paper, we propose a new method for simultaneously estimating the illumination of the scene and the reflectance property of the object from a single image. We assume that t...
