Pose refinement of active models using forces in 3D
A new algorithm is described for refining the pose of a model of a rigid object, to conform more accurately to the image structure. Elemental 3D forces are considered to act on the...

3D rotation invariant local binary patterns
We present a novel method for the fast computation of rotation invariant "local binary patterns" (LBP) on 3D volume data. Unlike a previous publication on 3D LBP, this n...

Image Thickness Correction for Navigation with 3D Intra-cardiac Ultrasound Catheter
Abstract. In this paper we present an algorithm to correct 3D reconstruction errors of 3D ultrasound catheter caused by ultrasound image thickness. We also provide a easy way to qu...

Maximizing Validity in 2D Motion Analysis
Classifying and analyzing human motion from a video is relatively common in many areas. Since the motion is carried out in 3D space, the 2D projection provided by a video is somew...

Sketching annotations in a 3D web environment
Collaborative design review is an important part of architectural design work. The Space Pen system supports annotation and drawing on (and inside) 3D VRML/Java models using a reg...
