In this paper, a new approach to thediscretization of n-dimensional Euclidean figures is studied: thediscretization of a compact Euclidean set K is a discrete set Swhose Hausdorff distance to K is minimal; in particular such adiscretization depends on the choice of a metric in the Euclideanspace, for example the Euclidean or a chamfer distance. We call sucha set S a Hausdorff discretizing set of K. The set ofHausdorff discretizing sets of K is nonvoid, finite, and closedunder union; we consider thus in particular the greatest one amongsuch sets, which we call the maximal Hausdorff discretization ofK. We give a mathematical description of Hausdorff discretizingsets: it is related to the discretization by dilationconsidered by Heijmans and Toet and the cover discretizationstudied by Andrès. We have a bound on the Hausdorff distancebetween a compact set and its maximal Hausdorff discretization, andthe latter converges (for the Hausdorff metric) to the compact setwhen the spacing of the discrete grid tends to zero. Such aconvergence result holds also for the discretization by dilation whenthe structuring element satisfies the covering assumption. Ourapproach is here the most general possible. In a next paper we willconsider the case where the underlying metric on points satisfiessome general constraints in relation to the cells associated to thediscrete points, and we will then see that these constraintsguarantee that the usual supercover and coverdiscretizations give indeed Hausdorff discretizing sets.
