# MagicData340K: A Large-Scale Dataset for Fine-Grained Artifacts Assessment in Text-to-Image Generation
This repository hosts **MagicData340K**, a large-scale human-annotated dataset central to the [MagicMirror framework](https://wj-inf.github.io/MagicMirror-page). The MagicMirror framework introduces a comprehensive approach for the systematic and fine-grained evaluation of physical artifacts (such as anatomical and structural flaws) in Text-to-Image (T2I) generation.
`MagicData340K` is the first human-annotated large-scale dataset, comprising 340,000 generated images, each with fine-grained artifact labels. These annotations are guided by a detailed taxonomy of generated image artifacts, making the dataset crucial for understanding and improving the perceptual quality of T2I models.

## Sample Usage
The MagicMirror framework, which utilizes this dataset, allows for the assessment of Text-to-Image (T2I) models. After setting up the environment as detailed in the [MagicMirror GitHub repository](https://github.com/wj-inf/MagicMirror), you can organize your image data (e.g., as `./output/sdxl/merged_result_sdxl.jsonl`) and run the assessment script:
```bash
bash run.sh flux-schnell sdxl
```
