• We propose a One-shot Diffusion Mimicker (One-DM) for stylized handwritten text generation, which only requires a single reference sample as style input, and imitates its writing style to generate handwritten text with arbitrary content.
• Previous state-of-the-art methods struggle to accurately extract a user's handwriting style from a single sample due to their limited ability to learn styles. To address this issue, we introduce the high-frequency components of the reference sample to enhance the extraction of handwriting style. The proposed style-enhanced module can effectively capture the writing style patterns and suppress the interference of background noise.
• Extensive experiments on handwriting datasets in English, Chinese, and Japanese demonstrate that our approach with a single style reference even outperforms previous methods with 15x-more references.

Overview of the proposed One-DM

• [2024/10/24] We have provided a well-trained One-DM checkpoint on Google Drive and Baidu Drive :)
• [2024/09/16] This work is reported by Synced (机器之心).
• [2024/09/07]🔥🔥🔥 We open-source the first version of One-DM that can generate the handwritten words. (Later versions supporting Chinese and Japanese will be released soon.)

conda create -n One-DM python=3.8 -y
conda activate One-DM
# install all dependencies
conda env create -f environment.yml

We provide English datasets in Google Drive | Baidu Netdisk | ShiZhi AI. Please download these datasets, uzip them and move the extracted files to /data.

Note: Please download these weights, and move them to /model_zoo. (If you cannot access the pre-trained VAE model available on Hugging Face, please refer to the pinned issue for guidance.)
