RA-L 2026

Efficient visual communication is critical for tetherless operation of underwater remotely operated vehicles, where acoustic links severely constrain bandwidth. Prior work introduced NVSPrior, which uses novel view synthesis with 3D Gaussian Splatting to encode scene priors, together with iNVS, a gr

Learning Environmental Structure Using Acoustic Probes with a Deep Neural Network

Toros Arikan, Amir Weiss, Hari Vishnu, Grant B. Deane, Andrew C. Singer, Gregory W. Wornell

ICASSP 2023accepted

Learning the physical environment is an important yet challenging task in reverberant settings such as the underwater and indoor acoustic domains. The locations of reflective boundaries, for example, can be estimated using echoes and leveraged for subsequent, more accurate localization. Current boun…
