The majority of image processing algorithms and architectures are designed to satisfy fixed performance constraints. Yet, time-varying constraints can be introduced by available energy (e.g., mobile devices), available wireless network bandwidth, user constraints, or the signal content itself. This talk will introduce a multi-objective optimization framework for designing jointly-optimal architectures and algorithms that can adapt to time-varying constraints. The solutions to such problems can be realized through the development of Dynamically Reconfigurable Architecture Systems for Time-varying Image Constraints (DRASTIC). Example of DRASTIC systems and applications in video communications, image and video analysis will be discussed in this talk. For video communications, the talk will present a DRASTIC DCT and HEVC implementations for implementing the maximum quality, minimum bitrate, minimum power, and typical modes. For image processing, the talk will present early work for developing scalable architectures for the Fast Discrete Periodic Radon Transform (FDPRT) that can be scaled to fit to hardware with different computational resources.

Biography: Marios Pattichis (M’99–SM’06) received the B.Sc.(High Hons. and Special Hons.) degree in computer sciences and the B.A. (High Hons.) degree in mathematics, both in 1991, the M.S. degree in electrical engineering in 1993, and the Ph.D. degree in computer engineering in 1998, all from the University of Texas, Austin. He is currently a Professor with the Department of Electrical and Computer Engineering, University of New Mexico (UNM), Albuquerque. His current research interests include digital image, video processing, communications, dynamically reconfigurable computer architectures, and biomedical and space image-processing applications. Dr. Pattichis is an Associate Editor for the IEEE Transactions on Image Processing, was an Associate Editor for the IEEE Transactions on Industrial Informatics, and has also served as a Guest Associate Editor for the IEEE Transactions on Information Technology in Biomedicine. For his development of the digital logic design labs at UNM , he was recognized by the Xilinx Corporation in 2003 and by the UNM School of Engineering’s Harrison faculty excellent award in 2006. At UNM , he is the director of the image and video Processing and Communications Lab at (ivPCL, ivpcl.org).
