WordCraft: Interactive Artistic Typography with Attention Awareness and Noise Blending

2025-07-13

AI Summary

Traditional artistic font generation suffers from limited interactivity: existing methods struggle with localized editing, iterative refinement, multi-character typographic coordination, and interpretation of abstract semantic prompts. This paper proposes a training-free interactive artistic font generation framework that synergistically integrates diffusion models with large language models (LLMs). We introduce a region-aware attention mechanism and a noise fusion technique to enable precise multi-region control and continuous optimization. Additionally, the LLM parses open-ended stylistic descriptions and structurally generates executable layout instructions, supporting cross-lingual, multi-character composition. Experiments demonstrate that our method preserves high character legibility and visual creativity in both single-character and multi-character scenarios, while significantly enhancing user-driven design flexibility and fine-grained controllability.

Abstract

Artistic typography aims to stylize input characters with visual effects that are both creative and legible. Traditional approaches rely heavily on manual design, while recent generative models, particularly diffusion-based methods, have enabled automated character stylization. However, existing solutions remain limited in interactivity, lacking support for localized edits, iterative refinement, multi-character composition, and open-ended prompt interpretation. We introduce WordCraft, an interactive artistic typography system that integrates diffusion models to address these limitations. WordCraft features a training-free regional attention mechanism for precise, multi-region generation and a noise blending that supports continuous refinement without compromising visual quality. To support flexible, intent-driven generation, we incorporate a large language model to parse and structure both concrete and abstract user prompts. These components allow our framework to synthesize high-quality, stylized typography across single- and multi-character inputs across multiple languages, supporting diverse user-centered workflows. Our system significantly enhances interactivity in artistic typography synthesis, opening up creative possibilities for artists and designers.
