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

Video available on video/lifebuoy_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': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=640x480>,
'image_path': 'images/Lifebuoy_Scene3_blur1_2.png',
'width': 640,
'height': 480,
'objects': {'id': [1],
'area': [7140.0],
'bbox': [[303.0, 248.0, 119.0, 60.0]],
'category': [0]}}
```
### Data Fields
- `image_id`: the image id
- `image`: the PIL image
- `image_path`: the image path
- `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` (3992)
- `Virtual`
- `Lifebuoy` (3992)
- `Val dataset` (998)
- `Virtual`
- `Lifebuoy` (998)
## Usage
```
from datasets import load_dataset
dataset = load_dataset("ARG-NCTU/Lifebuoy_dataset_2024")
```

## 数据集结构
### 数据实例
每个数据样本包含一幅图像及其目标标注信息。示例如下:
{'image_id': 1,
'image': <PIL.PngImagePlugin.PngImageFile image mode=RGB size=640x480>,
'image_path': 'images/Lifebuoy_Scene3_blur1_2.png',
'width': 640,
'height': 480,
'objects': {'id': [1],
'area': [7140.0],
'bbox': [[303.0, 248.0, 119.0, 60.0]],
'category': [0]}}
### 数据字段
- `image_id`:图像唯一标识符
- `image`:PIL格式图像
- `image_path`:图像文件路径
- `width`:图像宽度
- `height`:图像高度
- `objects`:包含图像内目标边界框元数据的字典,其子字段包括:
- `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
