frechet

Build Status Clojars Project CljDoc

A Clojure library to calculate the discrete Fréchet distance of two polygonal curves as stated by Eiter and Mannilla. The curves may be N-dimensional and need not be the same length.

Usage

Simply create 2D vectors with the points that describe the curves. In order to compute the frechet distance you need to provide a metric function to compute the distance between any point on the curves. The euclidean function is also part of the library for convenience.

(ns example.core
  (:require [carocad.frechet :as frechet]))

(frechet/distance [[1 2] [3 4]]
                  [[5 6] [7 8] [9 0]]
                  frechet/euclidean)
;; #:carocad.frechet{:distance 7.211102550927978, :coupling ([0 0] [1 1] [1 2])}
