GROUP THEORY, INVARIANCE & SYMMETRY IN VISION
One-day BMVA symposium on 21st January 2009.
Geometrical methods allow analysis of structures and their configuration
in a containing space. Group Theory provides an alternative perspective
analysis of structures, and their containing spaces in terms of
transformations of them. This transformation perspective leads to the
concept of invariant, intrinsic properties; to the concept of
symmetrical structures; allows a radically different characterization of
the geometry of a space; and allows reasoning and modelling in and of
the transformation space itself.
Group theory is a general tool of mathematical analysis, with
applications in most numerate disciplines but with a special
relationship with perception, as first noted by Helmholtz with his ideas
of constancy and later by Poincare who reasoned that perceptual
systems must be able internally to undo the effect of external
transformations.
New applications of Group Theory to Computational Vision continue to be
published. Some, for example understanding statistical shape variation
as a distribution over the group of diffeomorphisms, arise from the
general usefulness of Group Theory; others, for example invariant image
descriptors, are specific to vision.
This meeting is designed as a forum where work in these areas can be
presented and discussed. If you work on any of the topics below or any
related topic, or if you are interested in applying or learning about
them, do participate in the meeting and possibly present your work, even
if it is not fully developed or complete yet.
