Abstract :
The aim of this paper is to present two kinds of shape distances in a dynamic images context. The first distance is obtained by the complete and stable set of invariants under rigid motion for closed curves. The second distance is obtained by using a Hausdorff distance for parameter estimation. An original application serves as a useful test for evaluating these proposed distances in coding applications
