Abstract : Thinnings are very important operators for image analysis developed by mathematical morphology. Their most popular applications are the discrete homotopic skeletons. They are defined for sets as for functions but their use in the gray-scale case remains delicate and marginal. This article explores a variation of the thinning's original definition in which non significant local luminance variations are ignored. The derived simplified skeletons are presented on various examples.
