 This dataset contains images of boats for object detection tasks. It can be used to train and evaluate object detection models.
 
 ## Dataset Structure
-The dataset is organized as follows:
 
-- `images/`: This directory contains the boat images in JPG format.
-- `annotations/`: This directory contains the annotation files for each image in XML format.
-- `train.txt`: This file lists the file paths of the images used for training.
-- `test.txt`: This file lists the file paths of the images used for testing.
+### Data Instances
+
+A data point comprises an image and its object annotations.

+
+### 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 `BallonBoat` (0),`BigBoat` (1),`Boat` (2), `JetSki` (3), `Katamaran` (4), `SailBoat` (5), `SmallBoat` (6), `SpeedBoat` (7), and `WAM_V` (8).

-## Annotation Format
-The annotation files follow the PASCAL VOC format and contain bounding box annotations for each boat instance in the image.
 
 ## Usage
-To use this dataset, you can download the images and annotations from the following link: [Download Dataset](https://example.com/boat_dataset.zip)
+```
+from datasets import load_dataset
+dataset = load_dataset("zhuchi76/Boat_dataset")
