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 since September 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 (DTI
registration and clustering, heart motion analysis), computer vision
(segmentation of static and dynamic scenes, multiple view geometry, omnidirectional vision), machine learning (generalized
principal component analysis GPCA, kernel GPCA, dynamic GPCA), vision-based
coordination and control of unmanned vehicles, and hybrid systems
identification and control. 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 is a program chair for PSIVT 2007 and area chair for CVPR 2005 and ICCV 2007.
