title = "Geometric pattern matching in d-dimensional space",

abstract = "We show that, using the L∞ metric, the minimum Hausdorff distance under translation between two point sets of cardinality n in ddimensional space can be computed in time O(n(4d-2)/31og2 n) for d > 3. Thus we improve the previous time bound of O(n2d-2 log2 n) due to Chew and Kedem. For d = 3 we obtain a better result of O(n3 log2 n) time by exploiting the fact that the union of n axis-parallel unit cubes can be decomposed into O(n) disjoint axls-parallel boxes. We prove that the number of different translations that azhieve the minimum Hausdorff distance in dspace is Θ (n[3d/2]). Furthermore, we present an algorithm which computes the minimum Hausdorff distance under the L2 metric in d-space in time O(n[3d/2]+l log3 n).",
