Abstract. This paper addresses the problem of recovering the generating curve of a surface of revolution from a single uncalibrated perspective view, based solely on the object’s...
We present a procedure for tracking a rigid object based on a piecewise planar model, and show how it can be used to track a human face. The tracking is performed using a single in...
The application architecture of Newton, a technology for supporting Personal Digital Assistants (PDAs), is described. It combines a dynamic, object-oriented language called Newton...
For the purpose of Multimodal Meeting Manager Project (M4), an approach based on face and a hand tracking is proposed. The technique essentially includes skin color detection, seg...
This paper investigates the task of identifying frequently-used pathways from video sequences of natural outdoor scenes. Path models are adaptively learnt from the accumulation of...
