One Euro Filter

A fast and simple signal filter based on the work of Géry Casiez, Nicolas and Daniel Vogel.
The original research paper describing the algorithm can be found in the ACM digital library (paywalled) and further information, as well as other implementations, are available on the original author’s website.

Example

use one_euro_rs::OneEuroFilter;
// Set up the filter.
let frequency = 120.0;
let cutoff_min = 1.0;
let cutoff_d = 1.0;
let beta = 1.0;
let mut one_euro = OneEuroFilter::new(frequency, cutoff_min, cutoff_d, beta);
// Process some values.
one_euro.filter(1.0);
one_euro.filter(1.1);
one_euro.filter(0.9);
one_euro.filter(99999.9);
one_euro.filter(1.01);
one_euro.filter(1.04);
one_euro.filter(0.00);
