<!-- Provide a longer summary of what this dataset is. -->
This dataset contains video frames collected as part of the [Kenyan Animal Behavior Recognition (KABR)](https://imageomics.github.io/KABR/)
project at the [Mpala Research Center](https://mpala.org/) in Kenya in January 2023.
Sessions 1 and 2 are derived from the [full-length videos](https://huggingface.co/datasets/imageomics/KABR-mini-scene-raw-videos)
used in the [original KABR mini-scene release](https://huggingface.co/datasets/imageomics/KABR), now available in YOLO format.
Sessions 3, 4 and 5 are part of the [kabr-tools release](https://huggingface.co/datasets/imageomics/kabr-worked-examples),
derived from these [full-length videos](https://huggingface.co/datasets/imageomics/KABR-raw-videos).
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 YOLO format.
The dataset is designed to facilitate research in wildlife monitoring and conservation using advanced imaging technologies.
The dataset consists of 104,062 frames. Each frame is accompanied by annotations in YOLO format, indicating the presence of zebras and giraffes 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).

This table shows the data collected at Mpala Research Center in Laikipia, Kenya, with session information, dates, frame counts, and primary species observed.
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 named `<video_id_frame>.jpg`, each within a folder named for the date of the session. The annotations are in YOLO format and are stored in a corresponding .txt file with the same name as the image.
Note on data partitions: DJI saves video files into 3GB chunks, so each session is divided into multiple video files. 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. The original video files are not included in the dataset.
### Data Fields
**classes.txt**:
- `0`: zebra
- `1`: giraffe
- `2`: onager
- `3`: dog
Note: only zebras and giraffes appear in this dataset; onager and dog classes are included to be consistent across MMLA data collected at other locations,
see the MMLA datasets from [Ol Pejeta Conservancy](https://huggingface.co/datasets/imageomics/mmla_opc) and [The Wilds](https://huggingface.co/datasets/imageomics/mmla_wilds).
**frame_id.txt**:
- `class`: Class of the object in the image (`0` for zebra)
- `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
[More Information Needed] -->
<!--
Give your train-test splits for benchmarking; could be as simple as "split is indicated by the `split` column in the metadata file: `train`, `val`, or `test`." Or perhaps this is just the training dataset and other datasets were used for testing (you may indicate which were used).
-->
## 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.) -->
Please see the original [KABR mini-scene dataset](https://huggingface.co/datasets/imageomics/KABR) for more information on the source data.
#### 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 data was collected manually using a [DJI Air 2S drone](https://www.dji.com/support/product/air-2s). The drone was flown at the [Mpala Research Center](https://mpala.org/) in Laikipia, Kenya, capturing video footage of giraffes, Grevy's zebras, and Plains zebras in their natural habitat.
The videos were annotated manually using the Computer Vision Annotation Tool [CVAT](https://www.cvat.ai/) and [kabr-tools](https://github.com/Imageomics/kabr-tools). 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. -->

### Personal and Sensitive Information
The dataset was cleaned to remove any personal or sensitive information. All images are of Plains zebras, Grevy's zebras, and giraffes in their natural habitat, and no identifiable human subjects are present in the dataset.
<!--
For instance, if your data includes people or endangered species. -->
<!-- ## Considerations for Using the Data
[More Information Needed]
<!--
Things to consider while working with the dataset. For instance, maybe there are hybrids and they are labeled in the `hybrid_stat` column, so to get a subset without hybrids, subset to all instances in the metadata file such that `hybrid_stat` is _not_ "hybrid".
-->
<!-- ### Bias, Risks, and Limitations
[More Information Needed] -->
<!-- This section is meant to convey both technical and sociotechnical limitations. Could also address misuse, malicious use, and uses that the dataset will not work well for.-->
<!-- For instance, if your data exhibits a long-tailed distribution (and why). -->
<!-- ### Recommendations
[More Information Needed]
This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->
