Description
This dataset contains AI-based fish detections at the OBSEA Underwater Observatory (NW Mediterranean sea). The model is a YOLOv8 xlarge trained with labeled underwater pictures from OBSEA. The model can be found here.
A dolphin carcass found in the catalan coast was placed in front of the underwater camera to monitor the changes in the ecosystem produced by the presence of a big mammal carcass. The time coverage of the dataset is from 2024-05-30 to 2024-07-29.
