  Overview of Video Processing Methods and Picture Quality Optimization

  Tue, Apr 28, 2009 @ 11:00 AM - 12:00 PM

  Ming Hsieh Department of Electrical and Computer Engineering

  Conferences, Lectures, & Seminars

  
  

  Speaker: Dr. Jorge E. Caviedes,
  Intel Corporation,
  Chandler, ArizonaAbstract: This talk will present first an overview of the video processing methods for consumer applications, and discuss the components of the video processing chain and the overall processing characteristics. The second part will discuss how to achieve optimum picture quality with the video processing chain. The topics include video quality metrics, overall quality assessment, and methods to introduce automated quality control into the video processing chain.Biography: Dr. Caviedes is a Principal Engineer in the Digital Home Group of Intel Corporation, Chandler, Arizona. He is a multi-disciplinary scientist, expert in video/image processing and system design, no-reference quality metrics for enhanced/degraded video and their applications. He also serves as adjunct professor in the EE department of Arizona State University; co-founder and general co-chair of the annual International Workshop onVideo Processing and Quality Metrics for Consumer Electronics since 2005. Prior to Joining Intel in 2003, Dr. Caviedes was a Principal Member Research Staff at Philips Research. During his affiliation with Philips Research between 1987 and 2002 he worked in the labs at Briarcliff, NY, USA (1987-1998, 2001); Paris, France (1999-2000); and Eindhoven, the Netherlands (2002). In 1998, Dr. Caviedes was a Fulbright scholar at the University of the Andes where he taught graduate level courses on Medical Informatics. He has published over 35 technical papers, and holds 14 US patents (plus 23 pending).Host: Prof. Sanjit Mitra

  Capacity, Cooperation and Cognition in Wireless Networks

  Tue, Apr 28, 2009 @ 03:00 PM - 04:00 PM

  Speaker: Andrea Goldsmith,
  Stanford UniversityAbstract: We consider fundamental capacity limits in wireless networks where nodes can cooperate in transmission, reception, and relaying. The key to unlocking capacity of such networks is to characterize the impact of time-varying channels, interference, and feedback. A basic premise of our work is that the best way to manage interference is to exploit it, and such exploitation can lead to large capacity gains. In particular, we propose novel cooperative and cognitive radio methods that use signal transmissions overheard from other nodes to increase network capacity. We also extend these ideas to MIMO nodes, where the spatial dimension provides an additional design degree of freedom. New capacity results for time-varying multiuser channels with feedback and cooperation will also be presented. Finally, we will discuss the impact of feedback, cooperation, and channel dynamics on source-channel coding and separation optimalityBiography: Andrea Goldsmith is a professor of Electrical Engineering at Stanford University, and was previously an assistant professor of Electrical Engineering at Caltech. She is also co_founder and CTO of Quantenna Communications, Inc., and has previously held industry positions at Maxim Technologies, Memorylink Corporation, and AT&T Bell Laboratories. Her research includes work on wireless communication and information theory, MIMO systems and multihop networks, cross_layer wireless system design, and wireless communications for distributed control. She is author of the book ``Wireless Communications'' and co_author of the book ``MIMO Wireless Communications,'' both published by Cambridge University Press. She received the B.S., M.S. and Ph.D. degrees in Electrical Engineering from U.C. Berkeley. Dr. Goldsmith is a Fellow of the IEEE and of Stanford. She has received several awards for her research, including the National Academy of Engineering Gilbreth Lectureship, the Alfred P. Sloan Fellowship, the Stanford Terman Fellowship, the National Science Foundation CAREER Development Award, and the Office of Naval Research Young Investigator Award. In addition, she was a co_recipient of the 2005 IEEE Communications Society and Information Theory Society joint paper award. Dr. Goldsmith currently serves as associate editor for the IEEE Transactions on Information Theory and as editor for the Journal on Foundations and Trends in Communications and Information Theory and in Networks. She previously served as an editor for the IEEE Transactions on Communications and for the IEEE Wireless Communications Magazine, as well as guest editor for several IEEE journal and magazine special issues. Dr. Goldsmith participates actively in committees and conference organization for the IEEE Information Theory and Communications Societies and is an elected member of the Board of Governors for both societies. She is a distinguished lecturer for the IEEE Communications Society, the president of the IEEE Information Theory Society, and was the technical program co_chair for the 2007 IEEE International Symposium on Information Theory. She also founded the student committee of the IEEE Information Theory society and is an inaugural recipient of Stanford's postdoc mentoring award.Host: Urbashi Mitra, ubli@usc.edu, EEB 540, x04667
