The problem of inferring 3D orientation of a camera from video sequences has been mostly addressed by first computing correspondences of image features. This intermediate step is ...
The majority of methods available to recover 3D structure from video assume that a set of feature points are tracked across a large number of frames. This is not always possible i...
This paper describes a novel method for calibration of freehand three-dimensional (3D) ultrasound. A position sensor is mounted on a conventional ultrasound probe, thus the set of...
Topological relationships between spatial objects are an essential property of spatial objects. They are used for spatial analysis and query processing. In this paper, we first i...
