Speaker

Stephen C. North

Subject matter expert in graph visualization, visualization systems, applied algorithms

Stephen is Executive Director of Information Visualization Research. He works on systems and algorithms for visualizing and interactively exploring large, complex structures; and the general problem of applying computational geometry to visualization of abstract information with the goal of approaching the quality of hand-made graphics. Stephen is one of the authors of the Graphviz system. His group also created the core software for Vizgems, a software platform run by AT&T for its internal operations and enterprise customers. Vizgems collects, analyzes and displays near-realtime information at large scale for numerous managed services, and currently has about 100,000 endpoint devices. Stephen received a Ph.D. in Computer Science from Princeton University in 1986.

Amy R. Reibman

Subject matter expert in image and video quality estimation, and video transport over networks

Amy R. Reibman is a Lead Member of Technical Staff at AT&T Labs -- Research.  She received the B.S., M.S. and Ph.D. degrees in electrical engineering from Duke University in 1983, 1984, and 1987, respectively. From 1988 to 1991, she was an assistant professor in the Department of Electrical Engineering at Princeton University. In 1991 she joined AT&T Bell Laboratories, and became a Distinguished Member of Technical Staff in 1995. She is currently a Lead Member of Technical Staff in the Communication Sciences and Artificial Intelligence Research Department at AT&T Laboratories.

Dr. Reibman was elected IEEE Fellow in 2005, for her contributions to video transport over networks. In 1998, she won the IEEE Communications Society Leonard G.  Abraham Prize Paper Award.  She was the Technical co-chair of the IEEE International Conference on Image Processing in 2002; the Technical Co-chair for the First IEEE Workshop on Multimedia Signal Processing in 1997; the Technical Chair for the Sixth International Workshop on Packet Video in 1994.  She is currently technical co-chair for the Second International Workshop on Quality of Multimedia Experience, 2010.  She was a Distinguished Lecturer for the IEEE Signal Processing Society from 2008-2009.

Dr. Reibman's research interests include video compression systems for transport over packet and wireless networks, video quality estimation, superresolution image and video enhancement, and 3-D and multiview video.

Dr. Reibman's current goal is to improve overall system performance by integrating accurate video quality estimators into real systems.
