23rd International Conference on Distributed Computing Systems Workshops, 2003. Proceedings., 2004
Distance learning programs use on-line video records to deliver pre-recorded lectures. And, video communication systems can be used as a discussion tool. In this paper, we start our discussion on a multimedia presentation recording system which we had developed.

Proceedings of the IEEE, 1985
In this paper several video conferencing systems are discussed. These include single person-camera, voice-switched, split-screen, continuous presence, and virtual space systems. Special emphasis is placed on the more recent video conferencing systems, i.e., the continuous presence and the virtual space systems.

Education and Information Technologies, 2002
As a relatively new delivery medium, desktop video conferencing (DVC) promises to bring traditional face-to-face teaching to computer screens. Although ample literature covers incorporating technology into classrooms, little documents the experiences and perceptions of participants in DVC courses and DVC's effects on teaching and learning.

Color balance for video conferencing
Proceedings of International Conference on Image Processing, 2002This paper presents a method to color balance images. This method is useful for correcting images in video conferencing, where multiple video sources are displayed and each image has a different "look". The advantages of this approach are that it does not require a color reference object in each image, i.e.

Perceptions of proximity in video conferencing
CHI '02 extended abstracts on Human factors in computer systems - CHI '02, 2002Proximity is used as a non-verbal signal in face-to-face interaction. It is unknown whether similar information may exist during desktop video conferencing and if so what factors may regulate it. An experiment was conducted to compare the relative impact of image size and the scope of the image on users' impressions of proximity.

Honest signals in video conferencing
2011 IEEE International Conference on Multimedia and Expo, 2011We propose a novel system to analyze gestural and nonverbal cues of participants in video conferencing. These cues have previously been referred to as “honest signals” and are usually associated with the underlying cognitive state of the participants.

Ergonomics Aspects of Video Conferencing
2008Team cooperation in physically distributed design teams often uses video conferencing (VC) systems. Since humans have developed specific characteristics for interpersonal communication, VC should support such characteristics accordingly. Students were educated for such cooperation in masters design courses, where international, interdisciplinary teams ...

Active Lighting for Video Conferencing
IEEE Transactions on Circuits and Systems for Video Technology, 2009In consumer video conferencing, lighting conditions are usually not ideal thus the image qualities are poor. Lighting affects image quality on two aspects: brightness and skin tone. While there has been much research on improving the brightness of the captured images including contrast enhancement and noise removal (which can be thought of as ...

Distributed video conferencing systems
Computer Communications, 1997The emergence of the Internet as a global communications infrastructure has enabled the development of new distributed multiparty video conferencing solutions. These distributed solutions differ considerably from the circuit-switched centralized approaches which preceded them.
