Acoustic Image Source Interpolation with Optimal Transport Barycenter
Yuyang Liu, Rumeshika Pallewela, Jesper Brunnström +2
Room impulse responses can be estimated via the image source model (ISM) using the image source point cloud (ISPC) of a physical source. However, because the source movement change…

All-pole centroids in the Wasserstein metric with applications to clustering of spectral densities
Rumeshika Pallewela, Filip Elvander
In this work, we propose a method for computing centroids, or barycenters, in the spectral Wasserstein-2 metric for sets of power spectral densities, where the barycenters are rest…
