Moving frames
I will describe a new, practical approach to the theory
of moving frames. The method is completely algorithmic,
and applies to general Lie group actions, where it provides a rigorous
justification of Cartan's method, as well as infinite-dimensional
Lie pseudo-groups. Applications to differential invariants,
equivalence problems, symmetry, and rigidity, as well as image processing
and computer vision will be discussed.
