TextCtrl introduces a conditional diffusion model for scene text editing that integrates explicit prior guidance for text style and glyph structure, achieving improved style fidelity and text rendering accuracy. The method leverages multi-task pre-training for style disentanglement and a glyph-adaptive mutual self-attention mechanism for inference, and it contributes a new real-world evaluation dataset, ScenePair.
Key insights
- Explicitly disentangling and providing fine-grained prior guidance for both text style and glyph structure significantly enhances a diffusion model's ability to maintain style consistency and render text accurately.
- Font-variance augmentation during structure representation pre-training is crucial for achieving robust character-level glyph representations and improving text rendering accuracy in diverse scenarios.
- Dynamic, glyph-adaptive integration of source image features during inference can effectively reduce color deviation and texture degradation often encountered in diffusion-based image-to-image translation tasks.
