The Frechet distance is a measure of similarity between two curves, P and Q. It is defined as the minimum cord-length sufficient to join a point traveling forward along P and one traveling forward along Q, although the rate of travel for either point may not necessarily be uniform.

This algorithm calculates a bounded approximation of the Frechet distance using sampled points along curves P and Q.
