Appearance Characterization of Linear Lambertian Objects, Generalized Photometric Stereo, and Illumination-Invariant Face Recogn
Traditional photometric stereo algorithms employ a Lambertian reflectance model with a varying albedo field and involve the appearance of only one object. In this paper, we gene...

Photometric Stereo with Nearby Planar Distributed Illuminants
This paper considers the problem of shape-from-shading using nearby planar distributed illuminants. It is shown that a rectangular planar nearby distributed uniform isotropic illu...

Structured Light in Scattering Media
Virtually all structured light methods assume that the scene and the sources are immersed in pure air and that light is neither scattered nor absorbed. Recently, however, structur...

Reconstruction of snow and ice surfaces using multiple view  vision techniques
In this paper we describe a vision system for reconstructing the relative structure of snow and ice surfaces. This effort is one step toward the long-term goal of rendering absol...
