![title](https://curvesimilarities.readthedocs.io/en/latest/_images/plot-header.png)

A Numpy-friendly package for curve similarity measures.

List of supported measures:

- Dynamic time warping distance (`dtw()`)

- (Continuous) Fréchet distance (`fd()`)

- Discrete Fréchet distance (`dfd()`)

- Integral Fréchet distance (`ifd()`)

## Usage

```python

>>> import numpy as np

>>> from curvesimilarities import fd  # (Continuous) Fréchet distance

>>> fd(np.array([[0, 0], [1, 3], [2, 0]]), np.array([[0, 1], [2, 1]]))

2.0

```

## Installation

CurveSimilarities can be installed using `pip`.
