# Lifebuoy Underwater Dataset for Object Detection
## Overview
This dataset contains images of virtual underwater lifebuoy for object detection tasks. It can be used to train and evaluate object detection models.
Demo Example:

Video is available on video/lifebuoy_underwater_detection.mp4 or by clicking the image youtube link.
## Dataset Structure
### Data Instances
A data point comprises an image and its object annotations.
```
{'image_id': 1,
'image_path': 'images/Lifebuoy_Scene2_1.png',
'width': 640,
'height': 480,
'objects': {'id': [1],
'area': [7273.22705078125],
'bbox': [[316.0, 254.0, 106.0, 46.0]],
'category': [0]}}
```
### Data Fields
- `image_id`: the image id
- `width`: the image width
- `height`: the image height
- `objects`: a dictionary containing bounding box metadata for the objects present on the image
- `id`: the annotation id
- `area`: the area of the bounding box
- `bbox`: the object's bounding box (in the [coco](https://albumentations.ai/docs/getting_started/bounding_boxes_augmentation/#coco) format)
- `category`: the object's category, with possible values including
- `Lifebuoy` (0)
### Data Splits
- `Training dataset` (2396)
- `Virtual`
- `Lifebuoy` (2396)
- `Val dataset` (598)
- `Virtual`
- `Lifebuoy` (598)
## Usage
```
from datasets import load_dataset
dataset = load_dataset("ARG-NCTU/Lifebuoy_underwater_dataset_2024")
```

## 数据集结构
### 数据实例
每个数据点由一张图像及其目标标注信息组成。示例标注格式如下:
{'image_id': 1,
'image_path': 'images/Lifebuoy_Scene2_1.png',
'width': 640,
'height': 480,
'objects': {'id': [1],
'area': [7273.22705078125],
'bbox': [[316.0, 254.0, 106.0, 46.0]],
'category': [0]}}
### 数据字段
- `image_id`:图像唯一标识编号
- `width`:图像宽度
- `height`:图像高度
- `objects`:存储图像中目标边界框元数据的字典
- `id`:标注编号
- `area`:边界框的像素面积
- `bbox`:目标边界框,采用[COCO](https://albumentations.ai/docs/getting_started/bounding_boxes_augmentation/#coco)格式
- `category`:目标类别,可选值包括
- `救生圈(Lifebuoy)`(对应编号0)
### 数据划分
- 训练集(Training dataset):共2396条数据
- 虚拟场景(Virtual)
- 救生圈(Lifebuoy):2396条
- 验证集(Val dataset):共598条数据
- 虚拟场景(Virtual)
