H. Cho @[sprited](https://sprited.ai))  ## Model Summary **ToonOut** is a fine-tuned variant of **BiRefNet** specialized for **background removal in anime-style images**. BiRefNet performs strongly on realistic imagery but struggles with stylized content (e.g., hair wisps, line art, transparency). Fine-tuned on the [ToonOut Dataset](https://huggingface.co/datasets/joelseytre/ToonOut) (1,228 images), ToonOut delivers a notable boost for anime segmentation: - **Pixel Accuracy:** 95.3% → **99.5%** (on our test set) --- ## Model Details - **Architecture:** BiRefNet (fine-tuned) - **License:** MIT - **Training data:** [ToonOut Dataset](https://huggingface.co/datasets/joelseytre/ToonOut) (CC-BY 4.0) --- ## Example usage Please refer to [the demo notebook](https://github.com/MatteoKartoon/BiRefNet/blob/main/toonout_demo.ipynb) from our GitHub repo. --- ## Citation If you use ToonOut, please cite: ~~~bibtex @misc{muratori2025toonout, title={ToonOut: Fine-tuned Background Removal for Anime Characters}, author={Muratori, Matteo and Seytre, Joël}, year={2025}, eprint={2509.06839}, archivePrefix={arXiv}, primaryClass={cs.CV}, url={https://arxiv.org/abs/2509.06839}, doi={10.48550/arXiv.2509.06839} } ~~~ --- ## Authors & Contact - **Authors:** Matteo Muratori (University of Bologna, Kartoon AI), Joël Seytre (Kartoon AI) - **Contact:** joel@kartoon.ai, matteo.muratori9@studio.unibo.it ⸻ Project by *Kartoon AI*, powering **toongether**, check us out at [kartoon.ai](kartoon.ai) & [toongether.ai](toongether.ai)
