Keynote Lecture

Deformable Models and Sparse Methods for Improved Signal and Disease Diagnosis
Dimitri Metaxas
Rutgers University, USA

Abstract: We will present a cardiac system for motion analysis of the heart and disease diagnosis from MRI-tagged data, CT and ultrasound. Our system is based on the use of novel methods for segmentation and motion analysis which are based on sparsity and metamorphs. During the talk we will present details on these methods and will show cardiac motion analysis results for normal and pathologic hearts. Finally, we will also present our novel fluid simulation methods for visualization of patient specific cardiac blood flow.

Bio: Dr. Dimitris Metaxas is a Professor II (Distinguished) in the Computer Science Department at Rutgers. He got his PhD in 1992 from the University of Toronto and was a tenured faculty member at the University of Pennsylvania from 1992 to 2001. He is currently directing the Center for Computational Biomedicine, Imaging and Modeling (CBIM). Dr. Metaxas has been conducting research towards the development of formal methods upon which both computer vision, computer graphics and medical imaging can advance synergistically, as well as on massive data analytics problems. In computer vision, he works on the simultaneous segmentation and fitting of complex objects, shape representation, deterministic and statistical object tracking, learning, ASL, human activity recognition and security applications. In medical image analysis, he works on segmentation, registration and classification methods for cardiac and cancer applications. In computer graphics he is working on physics-based special effects methods for animation. He has pioneered the use of Navier-Stokes methods for fluid animations that were used in the Movie “Antz” in 1998. Dr. Metaxas has published over 350 research articles in these areas and has graduated 29 PhD students. His research has been funded by NSF, NIH, ONR, AFOSR and the ARO. Dr. Metaxas has published a book on his research activities titled "Physics-based deformable models: Applications to computer vision, graphics and medical imaging" which was published by Kluwer Academic. He is on the Editorial Board of Medical Imaging, an Associate Editor of GMOD, and CAD . Dr. Metaxas received several best paper awards for his work on in the above areas. He was awarded a Fulbright Fellowship in 1986, is a recipient of an NSF Research Initiation and Career awards, an ONR YIP, and is a Fellow of the American Institute of Medical and Biological Engineers, and member of ACM and IEEE. He has also been the Program Chair of ICCV 2007, the General Chair of MICCAI 2008 and ICCV 2011.
