Director, Vision Dynamics and Learning Lab
Research Interests: Medical learning; Computer vision; Biomedical image analysis; Dynamical systems; Robotics; Signal processing
Dr. René Vidal is a professor of biomedical engineering at the Whiting School of Engineering and the Johns Hopkins School of Medicine. His research focuses on biomedical imaging, computer vision and machine learning. Dr. Vidal serves as the director of the Vision Dynamics and Learning Lab in the Center for Imaging Science.
He is currently engaged in the development of mathematical methods for the interpretation of high-dimensional data, such as images, videos and biomedical data.
Dr. Vidal received his B.S. degree in electrical engineering (valedictorian) from the Pontificia Universidad Catolica de Chile in 1997. He earned his M.S. and Ph.D. degrees in electrical engineering and computer sciences from the University of California, Berkeley in 2000 and 2003, respectively. He was a research fellow at the National ICT Australia in 2003. He joined the Johns Hopkins faculty in 2004.
Dr. Vidal is the recipient of numerous awards for his work, including the 2012 J.K. Aggarwal Prize, the 2012 Best Paper Award in Medical Robotics and Computer Assisted Interventions (with Benjamin Bejar and Luca Zappella) and the 2011 Best Paper Award Finalist at the Conference on Decision and Control (with Roberto Tron and Bijan Afsari).
He is chair of the advisory board of the Computer Vision Foundation and associate editor of the journals Computer Vision and Image Understanding, Medical Image Analysis, IEEE Transactions on Pattern Analysis and Machine Intelligence and SIAM Journal on Imaging Sciences.
Dr. Vidal is a fellow of the International Association of Pattern Recognition and the Institute of Electrical and Electronics Engineers.

Research & Publications
As director of the Center for Imaging Science’s Vision Dynamics and Learning Lab, Dr. Vidal’s research focuses on several key areas:
- Biomedical image analysis: surgical gesture and skill recognition, analysis of high angular resolution diffusion imaging (HARDI), classification of stem cell derived cardiac myocites, interactive medical image segmentation
- Computer vision: camera sensor networks, activity recognition, dynamic texture segmentation and recognition, 3D motion segmentation, non-rigid shape and 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: observability, identification, realization, metrics and topology for hybrid systems
- Robotics: formation control of teams of non-holonomic robots, 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
Keen focus on the development of computational methods includes: 1) inferring models from images (image/video segmentation, motion segmentation), static data (subspace clustering) or dynamic data (identification of hybrid systems); and 2) using these models to accomplish a complex task, such as tracking fibers in the brain, recognizing actions in videos, landing a helicopter on a moving platform, pursuing a team of evaders or following a formation.
