By resizing the original images and converting them to the COCO format, this project provides an easier way to use DOTA with popular computer vision frameworks. Additionally, the dataset is formatted for seamless integration with Hugging Face datasets, unlocking new possibilities for training and experimentation. ## πŸ“‚ Dataset Structure ### COCO Format The dataset follows the COCO dataset structure, making it straightforward to work with: ```plaintext dota/ β”œβ”€β”€ annotations/ β”‚ β”œβ”€β”€ instances_train.json β”‚ β”œβ”€β”€ instances_val.json β”‚ └── instances_test.json β”œβ”€β”€ train/ β”œβ”€β”€ val/ β”œβ”€β”€ test/ ``` ### Hugging Face Format The dataset is compatible with the datasets library. You can load it directly using: ```python from datasets import load_dataset dataset = load_dataset("HichTala/dota") ``` ## πŸ–ΌοΈ Sample Visualizations Above: An example of resized images with bounding boxes in COCO format. ## πŸš€ Getting Started ### Install Required Libraries - Install datasets for Hugging Face compatibility: ```bash pip install datasets ``` - Use any object detection framework supporting COCO format for training. ### Load the Dataset #### Hugging Face: ```python from datasets import load_dataset dataset = load_dataset("HichTala/dota") train_data = dataset["train"] ``` #### Custom Script for COCO-Compatible Frameworks: ```python import json from pycocotools.coco import COCO coco = COCO("annotations/train.json") ``` see demo notebook [here](https://github.com/cocodataset/cocoapi/blob/master/PythonAPI/pycocoDemo.ipynb) for more details. ## βš™οΈ Preprocessing Details - Resizing: The original large images were split into smaller patches, each resized to *512x512 pixels*. - Annotations: Converted to COCO format for better compatibility and flexibility. ## πŸ“ How to Cite If you use this dataset, please consider citing the original DOTA dataset: ```plaintext Copy code @inproceedings{Xia_2018_CVPR, author = {Gui-Song Xia and Xiang Bai and Jieqing Zheng and others}, title = {DOTA: A Large-Scale Dataset for Object Detection in Aerial Images}, booktitle = {CVPR}, year = {2018} } ``` Additionally, you can mention this repository for the resized COCO and Hugging Face formats. Enjoy using DOTA in coco format for your object detection experiments! πŸš€
