This Friday, Prof. Gözde Bozdağı Akar is going to give a seminar on image and video compression for GATE 590 Graduate Seminar course. You are all kindly invited.

Bio: Gözde B. Akar received the B.Sc. degree from Middle East Technical University, Ankara, Turkey, in 1988 and the M.Sc. and Ph.D. degrees from Bilkent University, Ankara, Turkey, in 1990 and 1994, respectively, all in electrical and electronics engineering. She was with the University of Rochester, Rochester, NY, Center of Electronic Imaging Systems as a Visiting Research Associate from 1994 to 1996. From 1996 to 1998, she worked as a Member of Research and Technical Staff at Xerox Corporation Digital Imaging Technology Center, Rochester. From 1998 to 1999, she was with Baskent University, Department of Electrical and Electronics Engineering. During the summer of 1999, she worked as a Visiting Researcher at the Multimedia Laboratories, New Jersey Institute of Technology. Currently, she is a Professor with the Department of Electrical and Electronics Engineering, Middle East Technical University, Ankara, Turkey. Her research interests are in 2-D and 3-D video compression, single/multi-frame superresolution, radar signal processing.

Abstract: Video compression technologies are about reducing and removing redundant video data so that a digital video file can be effectively sent over a network and stored on computer disks. With efficient compression techniques, a significant reduction in file size can be achieved with little or no adverse effect on the visual quality. The video quality, however, can be affected if the file size is further lowered by raising the compression level for a given compression technique. The same arguments are also valid for image compression. In this talk, I will introduce the basic steps in video coding, algorithms used to measure quality and where the image/ video compression community is heading.
