Colloquium:Title: Computational Symmetry: By:Yanxi Liu, Associate Professor,Computer Science and Engineering,Penn State University
Symmetry is an essential mathematical concept, as well as a ubiquitous, observable phenomenon in nature, science and art. Either by evolution or by design, symmetry implies a potential structural efficiency gain that makes it universally appealing to computational science. Recognition and categorization of symmetry and regularity is the first step towards capturing the essential skeleton of a real world problem, while at the same time minimizing computational redundancy. In this talk, I will report my explorations in computational symmetry and symmetry groups applied in robotics, computer vision, and computer graphics. In particular I will describe the extraction/classification of crystallographic groups from real world, noisy visual and spatiotemporal data patterns, static and dynamic texture regularity and a computational characterization of statistical deviations from perfect symmetry.
