Bayesian Face Recognition with Deformable Image Models
We propose a novel representation for characterizing image differences using a deformable technique for obtaining pixel-wise correspondences. This representation, which is based o...

Model Based Analysis of Face Images for Facial Feature Extraction
This paper describes a comprehensive approach to extract a common feature set from the image sequences. We use simple features which are easily extracted from a 3D wireframe model ...

Rendering Tetrahedral Meshes with Higher-Order Attenuation Functions for Digital Radiograph Reconstruction
This paper presents a novel method for computing simulated x-ray images, or DRRs (digitally reconstructed radiographs), of tetrahedral meshes with higher-order attenuation functio...

Conveying three-dimensional shape with texture
Studies have shown that although shading can give an image a ”natural” look and is an important shape cue, visual perception of surface shape from shading only is severely lim...

Virtual Peg-in-Hole Performance Using a 6-DOF Magnetic Levitation Haptic Device: Comparison with Real Forces and with Visual Gui
We describe two experiments using three testbeds (real, virtual and vision-only) for comparison of user performance during 3-D peg-in-hole tasks. Tasks are performed using a six-d...
