Hyena ID 2022


This data set contains images of spotted hyena (Crocuta crocuta) with bounding boxes and individual animal identifications. This dataset represents a collaborative effort based on the data collection and population modeling efforts conducted by the Botswana Predator Conservation Trust. Photos (3,104) and metadata from various hyena encounters were collected. Images were annotated with bounding boxes around each visible hyena and viewpoints were labeled (e.g., left, right, etc.). A total of 256 individual spotted hyena were identified by their unique spot patterning using first computer-assisted spot pattern recognition and then manual review and confirmation. A total of 3,129 named sightings were exported.

Data format

The dataset is released in the Microsoft COCO .json format. We have collapsed the entire dataset into a single “train” label and have left “val” and “test” empty; we do this as an invitation to researchers to experiment with their own novel approaches for dealing with the unbalanced and chaotic distribution on the number of sightings per individual. All of the images in the dataset have been resized to have a maximum dimension of 2,400 pixels. The metadata for all animal sightings is defined by an axis-aligned bounding box and includes information on the rotation of the box (theta), the viewpoint of the animal, a species (category) ID, a source image ID, an individual string ID name, and other miscellaneous values. The temporal ordering of the images can be determined from the metadata for each image.
