## Wildlife Re-Identification (Re-ID) Datasets

The aim of the project is to provide a comprehensive overview of datasets for wildlife individual re-identification and an easy-to-use package for developers of machine learning methods. The core functionality includes:

- overview of 50 publicly available wildlife re-identification datasets and 2 metadatasets.
- utilities to mass download and convert them into a unified format and fix some wrong labels.
- used for training our models [MegaDescriptor](./megadescriptor.md) and [WildFusion](./wildfusion.md).
- synergy with [WildlifeTools](https://github.com/WildlifeDatasets/wildlife-tools) used for training ML models.

An introductory example is provided in a [Jupyter notebook](notebooks/introduction.ipynb). The package provides a natural synergy with [WildlifeTools](https://github.com/WildlifeDatasets/wildlife-tools), which provides our [MegaDescriptor](https://huggingface.co/BVRA/MegaDescriptor-L-384) model and tools for training neural networks. 

Do you know about any animal re-identification dataset which is not included? Post it to the [discussion forum](https://github.com/WildlifeDatasets/wildlife-datasets/discussions/6) please.

## Summary of datasets

An overview of the provided datasets is available in the [documentation](https://wildlifedatasets.github.io/wildlife-datasets/datasets/). We include basic characteristics such as publication years, number of images, number of individuals, dataset time spans (difference between the last and first image taken) and additional information such as source, number of poses, inclusion of timestamps, whether the animals were captured in the wild and whether the dataset contains multiple species.

## Installation

The installation of the package is simple by
```
pip install wildlife-datasets
```

## Adding new datasets

WildlifeDatasets are meant as a community effort to provide an easy access to wildlife re-identification datasets. New datasets may be easily added as described in the [documentation](https://wildlifedatasets.github.io/wildlife-datasets/adding/).

## Basic functionality

We show an example of downloading, extracting and processing the MacaqueFaces dataset.

```
from wildlife_datasets import analysis, datasets

datasets.MacaqueFaces.get_data('data/MacaqueFaces')
dataset = datasets.MacaqueFaces('data/MacaqueFaces')
```

The class `dataset` contains the summary of the dataset. The content depends on the dataset. Each dataset contains the identity and paths to images. This particular dataset also contains information about the date taken and contrast. Other datasets store information about bounding boxes, segmentation masks, position from which the image was taken, keypoints or various other information such as age or gender.

```
dataset.df
```

  <img alt="Overview of the MacaqueFaces dataset" src="https://github.com/WildlifeDatasets/wildlife-datasets/raw/main/docs/resources/MacaqueFaces_DataFrame.png">
</picture>

The dataset also contains basic metadata including information about the number of individuals, time span, licences or published year.

```
dataset.summary
```

<picture>
  <source media="(prefers-color-scheme: dark)" srcset="https://github.com/WildlifeDatasets/wildlife-datasets/raw/main/docs/resources/MacaqueFaces_Metadata_inverted.png">
  <source media="(prefers-color-scheme: light)" srcset="https://github.com/WildlifeDatasets/wildlife-datasets/raw/main/docs/resources/MacaqueFaces_Metadata.png">
  <img alt="Metadata of the MacaqueFaces dataset" src="https://github.com/WildlifeDatasets/wildlife-datasets/raw/main/docs/resources/MacaqueFaces_Metadata.png">
</picture>

This particular dataset already contains cropped images of faces. Other datasets may contain uncropped images with bounding boxes or even segmentation masks.

```
dataset.plot_grid()
```

## Additional functionality

For additional functionality including mass loading, datasets splitting or evaluation metrics we refer to the [documentation](https://wildlifedatasets.github.io/wildlife-datasets/) or the [notebooks](https://github.com/WildlifeDatasets/wildlife-datasets/tree/main/notebooks).
