Topological fingerprints for audio identification
Wojciech Reise, Ximena Fernández, Maria Dominguez +2
We present a topological audio fingerprinting approach for robustly identifying duplicate audio tracks. Our method applies persistent homology on local spectral decompositions of a…

Topological phase estimation method for reparameterized periodic functions
Thomas Bonis, Frédéric Chazal, Bertrand Michel +1
We consider a signal composed of several periods of a periodic function, of which we observe a noisy reparametrisation. The phase estimation problem consists of finding that repara…
