Resolution-Enhanced Photometric Stereo
Abstract. Conventional photometric stereo has a fundamental limitation that the scale of recovered geometry is limited to the resolution of the input images. However, surfaces that...

3-D Stereo Using Photometric Ratios
We present a novel robust methodology for corresponding a dense set of points on an object surface from photometric values, for 3-D stereo computation of depth. We use two stereo p...

High resolution catadioptric omni-directional stereo sensor for robot vision
Abstract − Autonomous robots need to acquire both omnidirectional view and stereo in real-time without sacrificing too much image resolution. The recent catadioptric omnidirectio...

Correction of Geometric and Photometric Distortion of Document Images Using a Stereo Camera System
In this paper, we propose a new method for correcting distorted document images using a stereo camera pair. Geometric and photometric distortions may occur in document images of t...

Isotropy, Reciprocity and the Generalized Bas-Relief Ambiguity
A set of images of a Lambertian surface under varying lighting directions defines its shape up to a three-parameter Generalized Bas-Relief (GBR) ambiguity. In this paper, we exami...
