Boundary-Informed Sound Field Reconstruction
David Sundström, Filip Elvander, Andreas Jakobsson
We consider the problem of reconstructing the sound field in a room using prior information of the boundary geometry, represented as a point cloud. In general, when no boundary inf…

Room Impulse Response Estimation through Optimal Mass Transport Barycenters
Rumeshika Pallewela, Yuyang Liu, Filip Elvander
In this work, we consider the problem of jointly estimating a set of room impulse responses (RIRs) corresponding to closely spaced microphones. The accurate estimation of RIRs is c…

Mixtures of ensembles: System separation and identification via optimal transport
Filip Elvander, Isabel Haasler
Crowd dynamics and many large biological systems can be described as populations of agents or particles, which can only be observed on aggregate population level. Identifying the d…
