- 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
- [2024/9/07]🔥🔥🔥 We open-source the first version of One-DM that can generate the handwritten words. (Later versions that can support 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
