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 YOLO format, indicating the presence of animals and their bounding boxes within the images. The annotations were completed manually by the dataset curator using [CVAT](https://www.cvat.ai/) and [kabr-tools](https://github.com/Imageomics/kabr-tools). | Session | Date Collected | Size (pixels) | Total Frames | Species | Drone Model | Video IDs |---------|---------------|---------------|--------------|-------------------|----------------|----------------| | `session_1` | 2024-06-14 | 2720 x 1530 | 13,749 | African Painted Dog | DJI Mini | DJI_0034, DJI_0035 | | `session_2` | 2024-04-18 | 4096 x 2160 | 4,053 | Persian Onanger | Parrot Anafi | P0100010, P0110011,P0080008, P0090009, P0070007, P0160016, P0120012 | | `session_3`| 2024-07-31 | 3840 x 2160 | 3,436 | Giraffe | Parrot Anafi | P0140018, P0150019| | `session_4` | 2024-07-31 | 4096 x 2160 | 506 | Grevy's Zebra | Parrot Anafi | P0070010 | | **Total Frames:** | | | **21,744** | | | This table shows the data collected at [The Wilds Conservation Center](https://www.thewilds.org/) in Ohio, USA, with session information, dates, frame counts, and primary species observed.

P0070010_000505.txt ``` ### Data Instances All images are named `_.jpg`, under the particular session and full video to which they belong; these can be matched to dates based on the table above. The annotations are in YOLO format and are stored in a corresponding `.txt` file with the same name as the image. Note: the DJI_0035 files are in .zip folders, due to issues uploading the large directories to HF. ### Data Fields **classes.txt**: - `0`: zebra - `1`: giraffe - `2`: onager - `3`: dog **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]) ### Data Splits This dataset was used in conjunction with the other two [MMLA datasets](https://huggingface.co/collections/imageomics/mmla) for both training and testing the [MMLA YOLO model](https://huggingface.co/imageomics/mmla#training-details). ## 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. ### Source Data #### Data Collection and Processing The African Painted Dog missions were collected manually using a [DJI Mavic Mini drone](https://www.dji.com/support/product/mavic-mini), while the Giraffe, Persian Onanger, and Grevy's Zebra missions were collected using a [Parrot Anafi drone](https://www.parrot.com/us/drones/anafi). The Grevy's zebras and giraffe missions were conducted semi-autonomously using the [WildWing system](https://imageomics.github.io/wildwing/), while the Persian onager data was collected manually. The drones were flown over the [Wilds Conservation Center](https://www.thewilds.org/) in Ohio, capturing video footage of the animals in their natural habitat. The videos were annotated manually using the Computer Vision Annotation Tool ([CVAT](https://www.cvat.ai/)) and the [kabr-tools](https://github.com/Imageomics/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 YOLO format, with bounding boxes indicating the presence of zebras in each frame. ### Annotations #### Annotation process [CVAT](https://www.cvat.ai/) and [kabr-tools](https://github.com/Imageomics/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 YOLO format. #### Who are the annotators?
