Project Description

Python/NumPy implementation of the Ramer-Douglas-Peucker algorithm (Ramer 1972; Douglas and Peucker 1973) for 2D and 3D data.

The Ramer-Douglas-Peucker algorithm is an algorithm for reducing the number of points in a curve that is approximated by a series of points.

Installation

pip install rdp

Usage

Simple pythonic interface:

from rdp import rdp

rdp([[1, 1], [2, 2], [3, 3], [4, 4]])
[[1, 1], [4, 4]]

With epsilon=0.5:

rdp([[1, 1], [1, 1.1], [2, 2]], epsilon=0.5)
[[1.0, 1.0], [2.0, 2.0]]

Numpy interface:

import numpy as np
from rdp import rdp

rdp(np.array([1, 1, 2, 2, 3, 3, 4, 4]).reshape(4, 2))
array([[1, 1],
       [4, 4]])
