DIOR Hugging Face-Ready Vision Dataset
This dataset is a restructured version of the DIOR (Object Detection in Optical Remote Sensing Images), specifically designed to simplify object detection workflows. By converting them to the COCO format, this project provides an easier way to use DIOR with popular computer vision frameworks. Additionally, the dataset is formatted for seamless integration with Hugging Face datasets, unlocking new possibilities for training and experimentation.
📂 Dataset Structure
COCO Format
The dataset follows the COCO dataset structure, making it straightforward to work with:
dior/
├── annotations/
│ ├── instances_train.json
│ ├── instances_val.json
│ └── instances_test.json
├── train/
├── val/
├── test/
Hugging Face Format
The dataset is compatible with the datasets library. You can load it directly using:
from datasets import load_dataset
dataset = load_dataset("HichTala/dior")
🖼️ Sample Visualizations
Above: An example of resized images with bounding boxes in COCO format.
🚀 Getting Started
Install Required Libraries
- Install datasets for Hugging Face compatibility:
pip install datasets
- Use any object detection framework supporting COCO format for training.
Load the Dataset
Hugging Face:
from datasets import load_dataset
dataset = load_dataset("HichTala/dior")
train_data = dataset["train"]
Custom Script for COCO-Compatible Frameworks:
import json
from pycocotools.coco import COCO
coco = COCO("annotations/train.json")
see demo notebook here for more details.
📚 Used in Research
This processed version of DIOR has been used in the paper:
📄 LoRA for Cross-Domain Few-Shot Object Detection
The dataset served as a target domain for evaluating the generalization capabilities of diffusion-based object detectors in low-data regimes.
