Port of the 1-euro filter algorithm for filtering noisy signals with adaptive low-pass filtering that balances jitter and lag.
Forks
Forks pushed to more recently than i-n-g-o/ofxOneEuroFilter itself, plus any admin-confirmed fork with commits of its own — worth checking if you're hitting issues with the original.
README
ofxOneEuroFilter
“The 1€ filter (“one Euro filter”) is a simple algorithm to filter noisy signals for high precision and responsiveness. It uses a first order low-pass filter with an adaptive cutoff frequency: at low speeds, a low cutoff stabilizes the signal by reducing jitter, but as speed increases, the cutoff is increased to reduce lag.” [Casiez 2012]
