Advanced Vision Analyzer, a Virtual Reality Perimeter

Active Vision and Virtual Reality

The experienced quality of virtual reality is currently limited by available computational resources, and will be for some time to come. It is essential that these limited resources not be wasted on the acquisition and processing of data that do not contribute significantly to the final percept. Efficient construction of the intermediate views that are the basis of some forms of virtual reality...

The Virtual Reality Revolution: The Vision and the Reality

Computer Vision Interaction for Virtual Reality

As virtual reality evolves towards more natural interfaces, new contact less interaction based on gesture recognition is unfolding. This interaction is supported on geometric, dynamic and cognitive modelling of gestures. As well as other branches of arti cial intelligence, computer vision plays an important role in this modelling. The purpose of this paper is to describe how computer vision is ...

Medical computer vision, virtual reality and robotics

The automated analysis of 3D medical images can improve both diagnosis and therapy significantly. This automation raises a number of new fascinating research problems in the fields of computer vision, graphics and robotics. In this paper, I propose a list of such problems after a review of the current major 3D imaging modalities, and a description of the related medical needs. I then present so...

Computer vision assisted virtual reality calibration

A computer vision assisted semi-automatic virtual reality (VR) calibration technology has been developed that can accurately match a virtual environment of graphically simulated three-dimensional (3-D) models to the video images of the real task environment. In conventional model-based computer vision, camera calibration and object localization are performed sequentially. This sequential update...
