	<!-- Provide a longer summary of what this dataset is. -->
	This dataset contains video frames collected at [The Wilds Conservation Center](https://www.thewilds.org/) 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 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).

	### Data Instances
	All images are named `<video_id>_<frame_number>.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

	<!-- Motivation for the creation of this dataset. For instance, what you intended to study and why that required curation of a new dataset (or if it's newly collected data and why the data was collected (intended use)), etc. -->

	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

	<!-- This section describes the source data (e.g., news text and headlines, social media posts, translated sentences, ...). As well as an original source it was created from (e.g., sampling from Zenodo records, compiling images from different aggregators, etc.) -->

	#### Data Collection and Processing

	<!-- This section describes the data collection and processing process such as data selection criteria, filtering and normalization methods, re-sizing of images, tools and libraries used, etc.
	This is what _you_ did to it following collection from the original source; it will be overall processing if you collected the data initially.
	-->

	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.

	<!-- #### Who are the source data producers?
	[More Information Needed] -->
	<!-- This section describes the people or systems who originally created the data.

	Ex: This dataset is a collection of images taken of the butterfly collection housed at the Ohio State University Museum of Biological Diversity. The associated labels and metadata are the information provided with the collection from biologists that study butterflies and supplied the specimens to the museum.
	-->


	### Annotations
	<!--
	If the dataset contains annotations which are not part of the initial data collection, use this section to describe them.

	Ex: We standardized the taxonomic labels provided by the various data sources to conform to a uniform 7-rank Linnean structure. (Then, under annotation process, describe how this was done: Our sources used different names for the same kingdom (both _Animalia_ and _Metazoa_), so we chose one for all (_Animalia_). -->


	#### 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.
	<!-- This section describes the annotation process such as annotation tools used, the amount of data annotated, annotation guidelines provided to the annotators, interannotator statistics, annotation validation, etc. -->

	#### Who are the annotators?

	<!-- This section describes the people or systems who created the annotations. -->
