About me
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). I am also a faculty member in the
Institute for Computational Medicine (ICM) and the
Laboratory for Computational Sensing and Robotics (LCSR). My research areas are biomedical image analysis, computer vision, machine learning, dynamical systems theory and robotics. Most of my 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 (track fibers in the brain, recognize actions in videos, land a helicopter on a moving platform, pursue a team of evaders, follow a formation, etc.)
Research Interests
Biomedical image analysis:
estimation and processing of high angular resolution diffusion imaging (HARDI),

Dynamical systems:
observability, identification, realization, metrics and topology for hybrid systems
Robotics:

coordination and control of multiple autonomous vehicles for pursuit-evasion games,
multiple view motion estimation and control for landing an unmanned aerial vehicle
Signal processing:
consensus on manifolds, distributed optimization, compressive sensing.
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.
Dr. Vidal was co-editor (with Anders Heyden and Yi Ma) of the book
``Dynamical Vision" and has co-authored more than 100 articles in
biomedical image analysis, computer vision, machine learning, hybrid
systems, and robotics. Dr. Vidal is Associate Editor of the Journal of
Mathematical Imaging and Vision, and was a program chair for WMVC
2009, PSIVT 2007 and area chair for CVPR 2005 and ICCV 2007.
Dr. Vidal is recipient of the
2009
ONR Young Investigator Award, the
2009
Sloan Research Fellowship, 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 is a member of the IEEE and the ACM.
