....Another way of measuring the resemblance between two polygons P and Q is by computing the area of their intersection (or, rather, of their symmetric difference) Suppose we wish to minimize the area of the symmetric difference between P and Q, under translation of P . For this case, de Berg et al. [86] gave an O(n log n) time algorithm, using the prune and search paradigm. Their algorithm can be extended to higher dimensions at a polylogarithmic cost, using parametric searching. 8.6 Surface simplification A generic surface simplification problem is defined as follows: Given a polyhedral ....

....result has consequences in shape matching in the plane. Given two convex polygons, P and Q, and a direction v, we can compute the translation of P in the direction v that has maximum intersection with Q or, equivalently, that minimizes the symmetric difference of P ffv and Q. De Berg et al. [3] have recently developed an O(n log n) algorithm to find the translation of P in any direction that has the maximum overlap with Q; their algorithm depends on this subroutine. Corollary 4.1 Given convex polygons P and Q, the magnitude ff of the translation along a given vector v that maximizes ....

....measure is a not a metric, since the triangle inequality does not hold. The invariance group is the class of di eomorphisms with unit Jacobi determinant. It turns out that translating the polygons so that their centroids coincide gives an overlap of at least 9 25 of the optimal solution [12]. For translations, the transformation that maximizes the area overlap also minimizes the area of symmetric di erence. 3.14 Area of Symmetric Di erence, Template Metric For two compact sets A and B, the area of symmetric di erence, also called template metric, is de ned as area( A B) B A) ....
