Several techniques for use in a stereo vision system are described. These include a stereo camera model solver, a high resolution stereo correlator for producing accurate matches with accuracy and confidence estimates, a search technique for using the correlator to produce a dense sampling of matched points for a pair of pictures, and a ground surface finder for distinguishing the ground from o...

Using 2D images is one of the most common techniques for the reconstruction of 3D face models. In this paper, we compare the strengths and weaknesses of different image processing techniques for 3D face generation. It is anticipated that the optimal solution will be applied in the future for 3D face analysis and synthesis. This paper presents binocular stereo using stereo correspondence algorit...

This paper describes a method for the calculation of surface reflectance values via photometric stereo. Experimental results show that surfaces rendered with reflectance values calculated by the proposed method have more realistic appearances than those with constant albedo. 1 Center for Image Technology and Robotics Tamaki Campus, The University of Auckland, Auckland, New Zealand. 2 Agilent Te...

By using mirror reflections of a scene, stereo images can be captured with a single camera (catadioptric stereo). Single camera stereo provides both geometric and radiometric advantages over traditional two camera stereo. In this paper; we discuss the geometry and calibration of catadioptric stereo with two planar mirrors and show how the relative orientation, the epipolar geometry and the esti...

Stereoscopy is a technique used for recording and representing stereoscopic (3D) images. It can create an illusion of depth using two pictures taken at two or more slightly different positions. There are two possible way of taking stereoscopic pictures by using special two-lens stereo cameras or systems with two single-lens cameras joined together. Stereoscopic pictures allow us to calculate th...

This paper describes a method for the estimation of surface reflectance values using a photometric stereo approach. Evaluations show that surfaces rendered with reflectance values calculated by the proposed method have more realistic appearances than those with constant albedo.

By using mirror reflections of a scene, stereo images can be captured with a single camera. Single camera stereo provides both geometric and radiometric advantages over traditional two camera stereo. In this paper, we discuss these advantages and show that the epipolar geometry is restricted to the class of planar motions. In addition we have implemented a real-time system which demonstrates th...
