Abstract
Perez and Vidal have proposed an optimal algorithm for the polygonal approx imation of digitized curves in 1994. The complexity of their algorithm is O ((PS)-S-2), where P is the number of points and S is the number of segments . We address the same problem using the framework of heuristic search strat egies to find the shortest path in a graph and show that the complexity of our algorithm is close to O(P-2).
