curve_similarities

Implementation of calculations for curves similarities as in python package similarity_measures.

The following distances are currently implemented:

• Frechet distance, from: Thomas Eiter and Heikki Mannila, Computing discrete Frechet distance. Technical report, 1994.
• Curve length measure, from: A Andrade-Campos, R De-Carvalho, and R A F Valente. Novel criteria for determination of material model parameters. International Journal of Mechanical Sciences, 54(1):294-305, 2012. ISSN 0020-7403. DOI URL

The library requires in input a bidimensional array of the ndarray rust library.

Examples

use curve_similarities::{frechet, DistMetric};
use ndarray::array;


fn main() {
    let fr = frechet(
        &array![[1.0], [1.0], [3.0]],
        &array![[2.0], [4.0]],
        DistMetric::Euclidean
    ).unwrap();

    println!("Frechet distance between curves is {}", fr);
}
