Discussion Meeting on
New Geometric Techniques in Computer Vision
Wednesday 23 July and Thursday 24 July 1997
at The Royal Society, 6 Carlton House Terrace, London SW1
Organized by R. Cipolla, J. Lasenby, H.C. Longuet-Higgins and A. Zisserman
Computer vision is the automatic analysis and interpretation of images of real
scenes. To date, geometric methods constitute the most useful tools for this
analysis. The adoption of projective geometry in the mid-1980's, as a
supplement to Euclidean geometry, provided a new approach to many computer
vision problems and has led to improved recognition methods and a better
understanding of the geometry of multiple views, particularly in the case of
uncalibrated cameras. A combination of differential geometry and motion
analysis has produced new algorithms for determining surface shape from the
temporal evolution of image curves, and a fusion of geometry and statistics has
resulted in powerful methods of tracking image features. The meeting will
describe recent developments in such techniques, including their implementation
in working systems.
