Date & Time: January 9, 2013 17:05
Venue: SIC First Floor Conference Room Kanwal Rekhi Building
Abstract:
This talk is about two of my recent research works. The first work concerns a reconstruction problem in multi-dimensional magnetic resonance imaging (specifically, high-angular-resolution diffusion imaging), using acquisition patterns with sub-Nyquist sampling rates. Our contributions involve a compressed-sensing formulation that proposes rotation-invariant dictionaries and combines them with overcomplete wavelet frames for signal modeling. The second work concerns analysis of shapes where each shape belongs to one of multiple groups within a population. Our contributions involve a hierarchical graphical model for shapes and an efficient sampling scheme in shape space. We show applications in hypothesis testing and classification.
