Dataset Details

This is a dataset containing annotated video frames of Plains zebras collected at the Ol Pejeta Conservancy (OPC) in Kenya using the autonomous WildWing system. 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 zebras in the images in COCO format. The dataset is designed to facilitate research in wildlife monitoring and conservation using advanced imaging technologies.

This dataset contains video frames collected from the WildWing system, which is an autonomous drone designed for wildlife monitoring.

The dataset includes frames from multiple sessions, over two days of data collection, 2025-01-31 and 2025-02-01, with a total of 5 videos. Each session captures video footage of Plains zebras in their natural habitat at the Ol Pejeta Conservancy in Kenya.

The dataset consists of 29,268 frames. Each frame is accompanied by annotations in COCO format, indicating the presence of zebras and their bounding boxes within the images. The annotations were completed manually by the dataset curator using CVAT and kabr-tools.

The dataset is intended for use in training and evaluating computer vision models for animal detection and classification from drone imagery.

This table shows the data collected at Ol Pejeta Conservancy in Laikipia, Kenya, with session information, dates, frame counts, and pixel resolution.

The dataset includes frames extracted from drone videos captured during five distinct data collection sessions. Each session represents a separate field excursion lasting approximately one hour, conducted at a specific geographic location. Multiple sessions may occur on the same day but in different locations or targeting different animal groups. During each session, multiple drone videos were recorded to capture animals in their natural habitat under varying environmental conditions.

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. 2025-01-31 and 2025-02-01 are the two days of data collection, with a total of 7 sessions. 2025-01-31 has 5 sessions and 2025-02-01 has 2 sessions.

Note on data partitions: HuggingFace limits folders to 10,000 files per folder, so each video file is further divided into partitions of 10,000 files. The partition folders are named partition_1, partition_2, etc.

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 data was collected using the WildWing system, which autonomously captures video footage of wildlife in their natural habitat. The data collection process involved flying the drone over the Ol Pejeta Conservancy in Kenya, where Plains zebras were observed. The missions were flown during the WildDrone Hackathon in January 2025, with the goal of capturing high-quality video footage for analysis.

The videos were annotated manually using the Computer Vision Annotation Tool CVAT and 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 zebras in each frame, drawing bounding boxes around them, and converting the annotations to COCO format.

Who are the annotators?

Personal and Sensitive Information

The dataset was cleaned to remove any personal or sensitive information. All images are of Plains zebras in their natural habitat, and no identifiable human subjects are present in the dataset.

Licensing Information

This dataset (the compilation) has been marked as dedicated to the public domain by applying the CC0-1.0 Public Domain Waiver. However, images may be licensed under different terms (as noted above).
