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…
Training-Free Temporal Abstraction for General Video Understanding
Etienne Casanova, Sevan Brodjian, Pietro Perona
Videos are expensive to analyze frame by frame, yet many video understanding tasks depend on knowing where relevant moments occur. A system may need to find when an action changes,…
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…
Kuramoto Orientation Diffusion Models
Yue Song, T. Anderson Keller, Sevan Brodjian +4
Orientation-rich images, such as fingerprints and textures, often exhibit coherent angular directional patterns that are challenging to model using standard generative approaches b…
