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 signatures of periodic-like signals
Wojciech Reise, Bertrand Michel, Frédéric Chazal
We present a method to construct signatures of periodic-like data. Based on topological considerations, our construction encodes information about the order and values of local ext…
