Dataset Card for wildwing-wilds

Dataset Details

This is a dataset containing annotated video frames of giraffes, Grevy's zebras, Persian onagers, and African Painted Dogs collected at The Wilds Conservation Center in Ohio. The dataset is intended for use in training and evaluating computer vision models for animal detection and classification from drone imagery. The dataset includes frames from various sessions, with annotations indicating the presence of animals in the images in COCO format. The dataset is designed to facilitate research in wildlife monitoring and conservation using autonomous drones.

Dataset Description

This dataset contains video frames collected at The Wilds Conservation Center in Ohio, USA, using drones. The Wilds is a 10,000 acre safari park and conservation center that is home to a variety of endangered species. The dataset includes video frames of African Painted Dogs, Giraffes, Persian Onangers, and Grevy's Zebras, captured during different sessions. The dataset is intended for use in training and evaluating computer vision models for animal detection and classification from drone imagery.

The dataset consists of frames. Each frame is accompanied by annotations in COCO format, indicating the presence of animals and their bounding boxes within the images. The annotations were completed manually by the dataset curator using CVAT and kabr-tools.

Data Instances

All images are names .jpg, each within a folder named for the date of the session. The annotations are in COCO format and are stored in a corresponding .txt file with the same name as the image.

Data Fields

classes.txt:

  • 0: dogs/giraffe/Onager/Zebra

frame_id.txt:

  • class: Class of the object in the image (0 for animal species)
  • x_center: X coordinate of the center of the bounding box (normalized to [0, 1])
  • y_center: Y coordinate of the center of the bounding box (normalized to [0, 1])
  • width: Width of the bounding box (normalized to [0, 1])
  • height: Height of the bounding box (normalized to [0, 1])

Dataset Creation

Curation Rationale

The dataset was created to facilitate research in wildlife monitoring and conservation using advanced imaging technologies. The goal is to develop and evaluate computer vision models that can accurately detect and classify animals from drone imagery, and their generalizability across different species and environments.

Data Collection and Processing

The African Painted Dog missions were collected manually using a DJI Mini drone, while the Giraffe, Persian Onanger, and Grevy's Zebra missions were collected using a Parrot Anafi drone. The Grevy's zebras and giraffe missions were conducted autonomously using the WildWing system, while the Persian onager data was collected manually. The drones were flown over the Wilds Conservation Center in Ohio, capturing video footage of the animals in their natural habitat.

The videos were annotated manually using the Computer Vision Annotation Tool (CVAT) and the kabr-tools library. These detection annotations and original video files were then processed to extract individual frames, which were saved as JPEG images. The annotations were converted to COCO format, with bounding boxes indicating the presence of zebras in each frame.

Annotations

Annotation process

CVAT and kabr-tools were used to annotate the video frames. The annotation process involved manually labeling the presence of animals in each frame, drawing bounding boxes around them, and converting the annotations to COCO format.
