Automatic resource allocation in a distributed camera network
In this paper, we present a hierarchical smart resource coordination and reconfiguration framework for distributed systems. We view the coordination problem as one of context aware resource reconfiguration. Th...

Generation and Error Characterization of Pararell-Perspective Stereo Mosaics from Real Video
There have been attempts in a variety of applications to add 3D information into an image-based mosaic representation. Creating stereo mosaics from two rotating cameras was proposed by [Huang & Hung, 1998], and f...

Trackability as a cue for potential obstacle identification and 3-D description
In many man-made environments, obstacles in the path of a mobile robot can be characterized asshallow, that is, they have relatively small extent in depth compared to the distance from the camera. We present a fr...
