Seminar by prof. Ken Rose (UCSB) at Politecnico

seminar_prof_rose1_smallThe Internet Media Group is delighted to host a seminar by prof. Kenneth Rose (UCSB) on “A common information framework for layered coding (and example application to audio)“.

The seminar will be held on Monday 12, 2014, at 14:30, in the Department of Control and Computer Engineering (DAUIN), meeting room 5th floor.

Abstract:
This talk revisits the question of scalable seminar_prof_rose3_smallcoding. Often the same content is served at different data rates and quality levels to various users. The simplest approach is to store and transmit independent copies of the signal at different quality levels, which is obviously wasteful in resources. The alternative approach of scalable coding imposes a rigid hierarchical structure, wherein the base layer information is subsumed in the higher layer information, and is widely recognized to incur a performance penalty compared to independent encoding. Instead of assuming such a rigid structure, we propose sharing only an appropriate subset (carefully selected) of base layer information with the enhancement layer. Concepts from classical Inforseminar_prof_rose2_smallmation theory (common information as defined by Wyner and by Gacs-Korner) provide a foundation and imply that this flexibility is indeed key to achieve efficiency in storing and transmitting signals at different quality levels, by optimally sharing information that is “common” to them. As an example, we then employ this framework to audio coding with the MPEG Scalable AAC and describe an optimization scheme to jointly select parameters of all the layers. Results for this coder provide practical evidence for the utility of such a flexible framework.

Kenneth Rose joined the Department of Electrical and Computer Engineering, University of California, Santa Barbara, in 1991 after receiving his Ph.D. from Caltech. His research activities are in the areas of information theory, signal compression, source-channel coding, video/audio coding and processing, pattern recognition, and nonconvex optimization. He is particularly interested in application of information and estimation theoretic approaches to fundamental problems in signal processing, as well as in the underlying relations between information theory and statistical physics. Recent research contributions of his group include methods for end-to-end distortion estimation in video transmission and streaming over lossy packet networks, optimal prediction in scalable video and audio coding, distributed source coding and sensor networks, as well as information theoretic approaches to optimization with applications in pattern recognition, signal compression and content-based search and retrieval from high-dimensional databases. His optimization algorithms have been adopted by others in numerous disciplines beside electrical engineering and computer science, including physics, chemistry, biology, medicine, materials, astronomy, geology, psychology, linguistics, ecology, and economics. Among various professional activities, Rose has served as an Area Editor for the IEEE Transactions on Communications, as a member of the IEEE Signal Processing Society’s Image and Multidimensional Signal Processing Technical Committee, and the Multimedia Signal Processing Technical Committee, and as co-Chair of the technical program committee of the 2001 IEEE Workshop on Multimedia Signal Processing, Cannes, France. He is a fellow of the IEEE and was the recipient or co-recipient of several journal and conference paper awards.

Abstract:
Recently, a quick increasing the amount and complexity of digital collections on Web requires the development of new treatment and search engines, methods and algorithms for multimedia information retrieval. Usually, the low-level features of images such as color, texture and shape are used for visual information processing. “High-level” methods try to recognize particular patterns and interpret content of whole image in order to make retrieval more efficient and reduce the number of searching iterations with nonsense results.
In this presentation some proposed hybrid approaches for visual information retrieval are discussed. They combine image low-level feature analysis with semantic descriptors of image content providing machine-understandable semantics for search, access, and retrieval of multimedia data using ontology. The results of our research may be used for development of image retrieval facilities such as, systems for supporting digital image processing services, design of software for high performance exchange of multimedia material within distributed collaborative and learning environments, distance education, digital libraries; design of searching facilities for personalized information among federated collections; image based navigators, etc.
