Addressing class imbalance in deep learning for acoustic target classification
Pala, Ahmet; Oleynik, Anna; Utseth, Ingrid; Handegard, Nils Olav (Journal article; Peer reviewed, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -

Simulations of multi-beam sonar echos from schooling individual fish in a quiet environment
Holmin, Arne Johannes; Handegard, Nils Olav; Korneliussen, Rolf J.; Tjøstheim, Dag (Peer reviewed; Journal article, 2012-12)A model is developed and demonstrated for simulating echosounder and sonar observations of fish schools with specified shapes and composed of individuals having specified target strengths and behaviors. The model emulates ... -
