Who I am
I am an assistant professor in the
Department of Biomedical Engineering at
The Johns Hopkins University. I direct the
Vision Dynamics and Learning Lab, which is part of the
Center for Imaging Science (CIS) and the
Institute for Computational Medicine (ICM). We are also afiliated with the
Laboratory for Computational Sensing and Robotics (LCSR). My research spans a wide range of areas in biomedical imaging, computer vision, machine learning, dynamical systems theory and robotics. Most of our work deals with the development of computational methods for (1) inferring models from images (image/video segmentation, motion segmentation), static data (subspace clustering) or dynamic data (identification of hybrid systems), and (2) using such models to accomplish a complex task (recognize actions in videos, land a helicopter on a moving platform, pursue a team of evaders, follow a formation, etc.)
Research Interests
Biomedical imaging: fiber tracing in the Purkinje network, segmentation and registration of diffusion weighted images, heart motion analysis
Computer vision: camera sensor networks, activity recognition, dynamic scene analysis, non-rigid motion analysis, structure from motion and multiple view geometry, omnidirectional vision
Machine learning: manifold clustering, kernels on dynamical systems, GPCA, kernel GPCA, dynamic GPCA
Dynamical systems: consensus on manifolds, observability, identification, and realization of hybrid systems
Robotics: vision-based control of unmanned ground and aerial vehicles
Brief Bio
Professor Vidal received his B.S. degree in Electrical Engineering (highest honors)
from the
Pontificia Universidad Catolica de Chile
in 1997 and his M.S. and Ph.D. degrees in
Electrical
Engineering and Computer Sciences from the University of California at Berkeley in 2000
and 2003, respectively. He was a research fellow at the
National
ICT Australia in the Fall of 2003 and joined
The Johns Hopkins University in January 2004
as an Assistant Professor in the
Department
of Biomedical Engineering and the
Center
for Imaging Science.
His areas of research are biomedical imaging, computer vision, dynamical systems, machine learning, and robotics.
Dr. Vidal is recipient of the 2005 NFS CAREER
Award and the 2004 Best Paper Award Honorable Mention (with Prof. Yi Ma)
for his work on "A Unified Algebraic Approach to 2-D and 3-D Motion
Segmentation" presented at the European Conference on Computer Vision.
He also received the
2004
Sakrison Memorial Prize for "completing an
exceptionally documented piece of research", the
2003
Eli Jury award for "outstanding achievement in the area of
Systems, Communications, Control, or Signal Processing", the 2002
Student Continuation Award from NASA Ames, the 1998 Marcos Orrego Puelma Award from the
Institute of Engineers of Chile, and the 1997 Award of the School of
Engineering of the Pontificia Universidad Catolica de Chile to the best graduating student of the
school. He was a program chair for PSIVT 2007 and area chair for CVPR 2005 and ICCV 2007. He is a member of the IEEE.
