H-thinning for gray-scale images

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 the sets as for the functions but their use in the gray-scale case remains delicate and marginal. This article explores one variation of the thinning's original definition in which the nonsignificant local variations of luminance are ignored. The simplified skeletons obtained are presented on various examples.
