Pure Maths Colloquium: Mathematical Problems in Computer Vision

Presented by "Peter J. Giblin, University of Liverpool",

8 March 2004 16:00 in CM221

"The attempt to automate recognition and classification of shapes in the plane and in 3 dimensional space has led to many mathematical problems. I shall concentrate in this talk on some of the ones in which I have been directly involved over the past 20 years or so and shall attempt to give an illustrated survey rather than a technical exposition. The topics include the reduction of a shape to a 'skeleton' of lower dimension which still contains a great deal of information about the shape; the recovery of shape from 'outlines' or 'apparent contours'; and the classification of views of illuminated surfaces.
