Time-frequency localization of bird calls in dense soundscapes
Simen Hexeberg, Fanghui Tong, Hari Vishnu +1
Passive acoustic monitoring enables large-scale observation of wildlife, but most bioacoustic classifiers only predict species presence in a time window without localizing vocaliza…
Passive Acoustic-based Composite Indices for Reef Health Monitoring in Noisy Tropical waters
Hari Vishnu, Yuen Min Too, Mandar Chitre +3
Passive acoustic monitoring offers the potential to enable long-term, spatially extensive assessments of coral reefs. To explore this approach, we deployed underwater acoustic reco…
Image Compression Using Novel View Synthesis Priors
Luyuan Peng, Mandar Chitre, Hari Vishnu +4
Real-time visual feedback is essential for tetherless control of remotely operated vehicles, particularly during inspection and manipulation tasks. Though acoustic communication is…
Joint Source-Environment Adaptation of Data-Driven Underwater Acoustic Source Ranging Based on Model Uncertainty
Dariush Kari, Hari Vishnu, Andrew C. Singer
Adapting pre-trained deep learning models to new and unknown environments remains a major challenge in underwater acoustic localization. We show that although the performance of pr…
