Computer Vision and Image Processing

John Barron's research interests lie in Computer Vision, in particular in the measurement and interpretation of 2D and 3D image motion. Recent work has included colour optical flow and recovery of 3D motion and scene depth in a Kalman filter framework. In addition, he is currently undertaking projects for storm detection and tracking in Doppler radar image sequences, for plant growth measurement via optical and range flow and 3D motion measurement in MRI cardiac sequences.

Mahmoud R. El-Sakka's research areas include: Image Compression and Encoding (both lossy and lossless), Image Understanding and Enhancement (with medical applications), Image Security (with application for financial documents) and Image Analysis/Inspection (with the goal of building an automatic label/bar-code inspection system).

Steven Beauchemin's interests are in the field of robotics and primarily deal with the computation of visual motion (optical flow) and its integration with other Computer Vision aspects, such as stereo vision and depth perception. He investigates and develops optical flow algorithms, especially for discontinuous motion, and studies motion-based autonomous navigation schemes. He is also developing new mathematical tools, such as alternate Fourier transforms.

Irene Gargantini began her carrier in information technology as a numerical analyst, and became known as the author of efficient approximations to complex mathematical functions--as those frequently involved in the neutron transport equation. In the early eighties, while at UWO, she became interested in the emerging fields of graphics and medical imaging, in particular problems dealing with data acquisition (enhancement, representation and visualization). Recent work deals with comparing the decomposition (truncated or not) of different wavelets for 2D and 3D acquired data (photographs, MRI, CT and US), and with the interactive visualization of volumes on the Web, implemented in a VRML environment ( www.csd.uwo.ca/VRML_Through_Viewer). Retired since June 2000, Prof. Gargantini is a professor emeritus and is still active in research and graduate student supervision. Her most recent publications can be found in http://www.csd.uwo.ca/faculty/irene.
