To define a dissimilarity measure between geometrical structures, we propose to use a representation of shapes with normal cycles (an object associated with the normal bundle of the shape which encodes all the curvature information). Using kernel metrics on normal cycles, we define a metric between shapes that fits in a framework of inexact registration. It allows for a matching that takes into account the region of high curvature and the boundaries of the shapes.
