Biography
John Barron, Professor, of department of Computer Science at University of Western Ontario, Canada.
Research Interest
Image Processing, Computer vision. My primary research interest is focused on the measurement and interpretation of optical flow. Recent work include using optical flow to measure corn seedling growth, a theoretical study of optical flow properties in the Fourier domain at occlusion boundaries, the recovery of 1st and 2nd order 3D motion parameters and 3D scene parameters (relative depth) from noisy optical flow using a Kalman filter framework. Another research area includes the use of time-varying range data for the measurement of range flow, the measurement of 3D (general) plant growth and the measurement of 3D motion and 3D structure (absolute depth) of a range sensor moving relative to a rigid/deformable environment. I am also interested in detecting and tracking severe weather storms in Doppler precipitation data and in using 3D storm velocity computed from Doppler radial velocity to aid in this tracking. Lastly, I am interested in computing 3D optical flow from gated MRI cardiac sequences.
