Abstract: This report describes the calculation of local errors in Chamfer masks both in
two- and in three-dimensional anisotropic spaces. For these errors, closed forms are given
that can be related to the Chamfer mask geometry. Thanks to these calculation, it can
be obsrved that the usual Chamfer masks (i.e. 3x3x3 or 5x5x5) have an inhomogeneously
distributed error. Moreover, it allows us to design dedicated Chamfer masks by controlling
