Eye Gaze Tracking Using an Active Stereo Head
In the eye gaze tracking problem, the goal is to determine where on a monitor screen a computer user is looking ? the gaze point. Existing systems generally have one of two limita...

Methods and Geometry for Plane-Based Self-Calibration
Abstract. We consider the problem of camera selfcalibration, from images of a planar object with unknown Euclidean structure. The general case of possibly varying focal length is a...

Stereo Correspondence with Slanted Surfaces: Critical Implications of Horizontal Slant
We examine the stereo correspondence problem in the presence of slanted scene surfaces. In particular, we highlight a previously overlooked geometric fact: a horizontally slanted ...

Tracking of the Articulated Upper Body on Multi-View Stereo Image Sequences
We propose a novel method for tracking an articulated model in a 3D-point cloud. The tracking problem is formulated as the registration of two point sets, one of them parameterise...
