Impact of Glyph Information on Latent Space Diffusion Models for Accurate Handwritten Text Generation

Abstract

The generation of high-quality stylized handwritten text images is a challenging task in computer vision and artificial intelligence. While advanced approaches using Latent Diffusion Models (LDMs) for generating stylized handwritten text have shown effectiveness, they often struggle with maintaining the structural integrity of certain characters, resulting in issues such as missing or extraneous strokes. In this work, we propose GlyphLDM, an innovative model that integrates glyph image information into both the diffusion and denoising processes in the latent space, enhancing the structural accuracy of generated text images. In the early training stages, our method demonstrated a significant improvement in the structural accuracy of the generated text images, with the Average Confidence Score increasing by approximately 40% compared to the baseline method. These experimental results indicate that incorporating glyph image information has promising potential to enhance the structural accuracy and overall quality of generated text images. This approach provides an effective solution for generating more accurate and diverse handwritten text images.
