Professor Joseph RONSIN comes from Institut National des Sciences Appliquées (INSA- Institute of Applied Sciences) in Rennes, in France. His research interesting is image processing and pattern recognition theory. He will give a group of lectures on image representation and compression.

Academic activities schedule

Professor:Joseph RONSIN Subject direction:Signal and Image Processing

IMAGE REPRESENTATION and COMPRESSION

Lectures are dedicated to source coding of still images and video. These lectures must permit the apprehension of the essential aspects of representation and compression for images. Representation has the objective of a reduction of corresponding data. After some brief reminders on Information Theory and human vision, then using Signal Theory, main coding techniques will be presented and illustrated. Standards for still images: JPEG and JPEG 2000 will be introduced with also standards for video: MPEG-1,2,4. Exercises will be developed in parallel, on one hand at the blackboard and on the other hand with dedicated software.

Resume of Joseph RONSIN

Joseph RONSIN was born in 1948. He obtained an M.Sc. in Electronics from the University of Rennes, France, in 1972. He joined, as a lecturer Institut National des Sciences Appliquées (INSA- Institute for Applied Sciences) in Rennes, and obtained his D.Sc. in 1977. He became Director de Recherches in 1989 and Professor one year later. Joseph RONSIN is now Professor in the Department of Electronic and Computer engineering of INSA and is responsible for research of Image and Remote sensing group of Institut d’Electronique et Télécommunications de Rennes (IETR- Institute of Electronics and Telecommunications of Rennes). The Rennes Institute of Electronics and Telecommunications brings together research teams working in the fields of electronics and telecommunications at the University of Rennes 1 and the Rennes Institute for Applied Sciences (INSA). With more than 300 people, the unit is linked to French National Center for Scientific Research (CNRS) and places the emphasis on developing the skills needed to explore a wide range of emerging applications.

IETR is structured on 5 groups. The Image and Remote sensing group for INSA component, has 10 professor and assistant professor, 16 PhD students, 2 research-engineers and focuses its research activities on these three topics:

· Representation and compression of video frames and sequences,

· Analysis and interpretation of remote sensing images,

· Prototyping on parallel and mixed architectures.

Joseph Ronsin has been responsible for several industrial grants with state or private Laboratories, in the fields of Image analysis or Image compression. He is author of more than 130 publications and communications.
