✦ Synopsis

The aim of this paper is to present two kinds of shape distances in a dynamic image context. Both are de"ned for closed curves. The "rst distance is obtained by invariant descriptors, under rigid motion, which verify a completeness and stability properties. The second one distance obtained by a Hausdor! distance that allows to estimate the motion parameters. These distances are tested on real images.
