Title of talk: "Image registration by matrix Lie groups actions"

Abstract: In this talk we consider the problem of registration of two
images. We consider global transformations of the domain, viewed as an
homogeneous manifold (subgroups of GL(n) acting on Omega, the image
domain, subset of R^n).  The registration problem is then rephrased as
a minimization problem on a Lie group. Several intrinsic methods (like
steepest descent and Newton's method on a manifold) will be
considered.
