Original provider: Duke Marine Robotics and Remote Sensing Lab Dataset credits: Duke Marine Robotics and Remote Sensing Lab Abstract: These RGB mosaics and thermal indices of Atlantic grey seal colonies at Hay and Saddle Island, Nova Scotia, were collected by small unmanned aircraft systems (UAS). The mosaics and thermal indices were assessed by human analysts, who counted the seals in the mosaic and classified individuals as 'young of the year' or 'adult'. Concurrently, an automated detection and classification model was applied to the datasets and compared to human counts.
