Teleconferencing for Virtual Visiting Professors and Virtual Grand Rounds

Visiting Professors

are called upon to undertake a great deal of work which is outside their terms of contract and which often takes them away for appreciable periods of time. The universities recognize this, for the work which is done in this way often helps to bring credit to the university and the contacts which are made bring distinguished visitors and may also attract junior staff and research workers of high...

Human figure synthesis and animation for virtual space teleconferencing

Human figure animation is a widely researched area with many applications. This paper addresses specific issues that deal with the synthesis, animation and environmental interaction of human figures within a virtual space teleconferencing system. A layered representation of the human figure is adopted. Skeletal posture is determined from magnetic sensors on the body, using heuristics and invers...

Teleconferencing Eye Contact Using a Virtual Camera

To preserve eye contact in teleconferencing both the camera and the monitor need to be positioned on the same optical axis which, in practice, is usually not possible. We propose a method to construct the view from a virtual coaxial centered camera given two cameras mounted on either side of the monitor. Stereoscopic analysis of the two camera views provides a partial three-dimensional descript...

Synthetic Natural Hybrid Video Processings for Virtual Teleconferencing Systems

In this paper, we propose powerful virtual image processing tools, which can be useful for designing new virtual teleconferencing systems with limited bandwidth requirements. We present an integrated approach that mixes real images with computer graphics in order to obtain an efficient and highly realistic model-based coding scheme, while offering new possibilities from the point of view of the...
