CFC26: Building Evaluations for Deployment in Sonar-Based Fish Counting
Madison Van Horn, Suzanne Stathatos, Sevan Brodjian +6
Accurate counts of fish populations are essential for monitoring ecosystems and making decisions for conservation, harvest limits, and river management. In many field deployments,…
When Generative Models Act as Simulators
Sevan Brodjian, Michael Hobley, Pietro Perona
A simulator summarizes an environment in a state that users can read and change. Generative models learn representations of the world without explicit specification, but offer no b…
Single View Seafloor Recovery from Imaging Sonar via Differentiable Rendering
Sevan Brodjian, Michael Hobley, Pietro Perona
Sonar is often the only modality suitable for high-resolution imaging underwater due to light attenuation and turbidity. Forward-looking imaging sonar provides measurements over ra…
SAVeD: Learning to Denoise Low-SNR Video for Improved Downstream Performance
Suzanne Stathatos, Michael Hobley, Pietro Perona +1
Low signal-to-noise ratio videos -- such as those from underwater sonar, ultrasound, and microscopy -- pose significant challenges for computer vision models, particularly when pai…
