Abstract:
Recent advances in deformable models have lead to new classes of methods
that borrow the best features form level sets as well as traditional
parametric deformable models. In this talk I will first present a new
class of such models termed Metamorphs whose formulation integrates
shape, intensity and texture by borrowing ideas from level sets and
traditional parametric deformable models. Further extensions to these
models include the inclusion of shape and texture priors. These new
models can be used in medical segmentation and registration where organ
boundaries are fuzzy and with no assumptions on the noise distribution.
Applications include cancer and cardiac detection and anaysis. In the
second part of the talk, I will discuss some recent advances in sparse
matrix methods capable of segmenting and tracking complex phenomena such
as waterfalls. Finally, I will
conclude with a novel method for fluid modeling which allows the
simulation of coupled fluid-deformable object interactions at very fine
scales.
Bio:
Dr. Dimitris Metaxas is a Professor II (Distinguished) in the Division
of Computer and Information Sciences and Professor II in the Department
of Biomedical Engineering at Rutgers University. 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. In computer vision, he
works on the simultaneous segmentation and fitting of complex objects,
shape representation, deterministic and statistical object tracking,
learning and ASL, and human activity recognition. Dr. Metaxas has
published over 300 research articles in these areas and has graduated 26
PhD students. His research has been funded by NSF, NIH, ONR, AFOSR and
the ARO. He is on the Editorial Board of Medical Imaging, as 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. He was also the Program
Chair of ICCV 2007 and the General Chair of MICCAI 2008.
