AI Mosquito Alert Challenge Dataset 2023

The AI Mosquito Alert 2023 Challenge Dataset is a curated dataset used in the AI Mosquito Alert 2023 Challenge (https://www.aicrowd.com/challenges/mosquitoalert-challenge-2023), aimed at improving mosquito species identification through AI and deep learning models.

This dataset is distributed under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License (CC BY-NC-SA 4.0): https://creativecommons.org/licenses/by-nc-sa/4.0/.

The dataset was created through the efforts of the Mosquito Alert team, collaborators and thousands of citizen scientists. Please credit the Mosquito Alert Community (www.mosquitoalert.com) if you use this dataset (e.g., 'Mosquito Alert dataset, downloaded from [link], CC BY-NC-SA 4.0').

The intellectual property (IP) rights of this dataset belong to the Mosquito Alert team. 

The license is included in the file license.txt within the dataset zip file, along with the images, labels and dataset description.

The dataset consists of 10357 labeled images (approximately 9.8 GB in total). Images are accompanied by a designated CSV file called: annotations.csv. The CSV files include bounding box coordinates in the format: top left and bottom right notation ("bbx_xtl", "bbx_ytl", "bbx_xbr", "bbx_ybr").

The dataset consists of six distinct classes, including species and genus levels as well as a species complex. 

A summary of the mosquito classes, their descriptions, and corresponding class names used in the dataset:

Aedes aegypti (species level) - class name: "aegypti"

Aedes albopictus (species level) - class name: "albopictus"

Anopheles (genus level) - class name: "anopheles"

Culex (genus level) - class name: "culex" (species classification is challenging, so it is given at the genus level)

Culiseta (genus level) - class name: "culiseta"

Aedes japonicus/Aedes koreicus (species complex - difficult to differentiate between the two species) - class name: "japonicus-koreicus"

Label file:

The dataset includes a single CSV file: annotations.csv, which contains all the annotations for the images. Each row in the file provides the following information:

img_fName: image file name

img_w: image width

img_h: image height

bbx_xtl: bounding box top-left x-coordinate

bbx_ytl: bounding box top-left y-coordinate

bbx_xbr: bounding box bottom-right x-coordinate

bbx_ybr: bounding box bottom-right y-coordinate

class_label: class label (e.g., 'albopictus').

Additional notes:

a broader description of the dataset and classes will be provided in the https://www.aicrowd.com/challenges/mosquitoalert-challenge-2023#dataset and https://www.youtube.com/watch?v=qSWJZUY-5DM challenge video

exif information has been removed from the images for privacy protection

most images contain a single mosquito with its corresponding bounding box and class label. However, in rare cases with multiple mosquitoes, only one mosquito is assigned a bounding box and label for consistency and compatibility.

AI蚊子警报（AI Mosquito Alert）2023挑战赛数据集是为AI蚊子警报2023挑战赛（https://www.aicrowd.com/challenges/mosquitoalert-challenge-2023）打造的精选数据集，旨在通过人工智能与深度学习模型提升蚊虫物种识别精度。

本数据集由蚊子警报团队（Mosquito Alert team）、合作方以及数千名公民科学家共同打造。若使用本数据集，请注明来源为蚊子警报社区（Mosquito Alert Community，www.mosquitoalert.com），示例标注格式为：'Mosquito Alert dataset, downloaded from [link], CC BY-NC-SA 4.0'。

本数据集的知识产权（Intellectual Property, IP）归属于蚊子警报团队。

数据集压缩包内的license.txt文件中包含本许可协议，同时该文件与数据集图片、标注文件及数据集说明一同收录于压缩包中。

本数据集包含10357张带标注的图片，总容量约9.8 GB。配套有专属的CSV标注文件`annotations.csv`，该文件采用左上-右下坐标格式记录边界框（bounding box）信息，字段为`bbx_xtl`、`bbx_ytl`、`bbx_xbr`、`bbx_ybr`。

本数据集共包含6个明确的分类类别，涵盖物种级、属级以及物种复合群。

以下为蚊虫分类类别汇总、类别说明及数据集中使用的对应类别名称：

1. 埃及伊蚊（Aedes aegypti，物种级）- 类别名称："aegypti"
2. 白纹伊蚊（Aedes albopictus，物种级）- 类别名称："albopictus"
3. 按蚊属（Anopheles，属级）- 类别名称："anopheles"
4. 库蚊属（Culex，属级）- 类别名称："culex"（该类群物种分类难度较高，故采用属级标注）
5. 寒蚊属（Culiseta，属级）- 类别名称："culiseta"
6. 日本伊蚊/朝鲜伊蚊复合群（物种复合群，二者难以区分）- 类别名称："japonicus-koreicus"

| 类别名称 | 图片数量 |
|----------|----------|
| aegypti | 47 |
| albopictus | 4612 |
| anopheles | 84 |
| culex | 4563 |
| culiseta | 622 |
| japonicus-koreicus | 429 |
| 总计 | 10357 |

### 标注文件说明
本数据集仅包含一个CSV标注文件：`annotations.csv`，收录所有图片的标注信息。文件中每一行包含以下字段：
- `img_fName`：图像文件名
- `img_w`：图像宽度
- `img_h`：图像高度
- `bbx_xtl`：边界框左上角X坐标
- `bbx_ytl`：边界框左上角Y坐标
- `bbx_xbr`：边界框右下角X坐标
- `bbx_ybr`：边界框右下角Y坐标
- `class_label`：类别标签（示例：'albopictus'）

### 附加说明
1. 本数据集及类别的更详细说明可访问挑战赛页面：https://www.aicrowd.com/challenges/mosquitoalert-challenge-2023#dataset，或查看挑战赛视频：https://www.youtube.com/watch?v=qSWJZUY-5DM。
2. 为保护隐私，已移除所有图片的EXIF元数据。
3. 绝大多数图片仅包含单只蚊虫，并配有对应的边界框与类别标签。极少数多蚊虫场景中，为保证数据一致性与兼容性，仅为其中一只蚊虫标注边界框及类别标签。
