This course provides an introduction to the basic concepts and techniques used for the compression of digital images and video. Video compression requirements, algorithm components, and ISO Standard video processing algorithms are studied. Image compression components that are used in video compression methods are also identified. Since many of the capabilities of these standards are still being developed, and have not been integrated into computer and communication systems, the study of the component technologies will provide guidelines for evaluation and selection when the standards are approved. Topics to be covered include: introduction to video systems, Fourier analysis of video signals, properties of the human visual system, motion estimation, basic video compression techniques, video communication standards, and error control in Video Communications. A mini-project is required.
This course is offered in the fall semester.

Nicholas Beser received a Ph.D. in 1983 in systems engineering and computer science from the University of Pennsylvania. Dr. Beser has worked at the Johns Hopkins University Applied Physics Laboratory for over 15 years. Currently, he is Assistant Section Supervisor for the Knowledge Discovery Section of the Intelligence Systems Group. Dr. Beser is the Project Manager for the Multimedia Forensic Laboratory and is the Chief Engineer on the Digital Video Authentication Project. He has also been the lead researcher at on several Video Exploitation IR&D projects developing video mosaic, super-resolution, and automated scene change detection methods. In addition, he has supplied video exploitation services to both Howard County Police and Baltimore City Police in the analysis and enhancement of crime video tapes. Dr. Beser is the JHU/APL representative to the International Standards Organization Moving Pictures Experts Group (MPEG) Panel. He has authored many papers on data compression standards, history of space data compression, and data compression quality measures. In addition, he also has extensive work experience in the area of high-speed signal and data processing covering both design and software.
