TextFlux: An OCR-Free DiT Model for High-Fidelity Multilingual Scene Text Synthesis

TextFlux is an OCR-free framework using a Diffusion Transformer (DiT, based on FLUX.1-Fill-dev) for high-fidelity multilingual scene text synthesis. It simplifies the learning task by providing direct visual glyph guidance through spatial concatenation of rendered glyphs with the scene image, enabling the model to focus on contextual reasoning and visual fusion.

Key Features

OCR-Free: Simplified architecture without OCR encoders.
High-Fidelity & Contextual Styles: Precise rendering, stylistically consistent with scenes.
Multilingual & Low-Resource: Strong performance across languages, adapts to new languages with minimal data (e.g., <1,000 samples).
Zero-Shot Generalization: Renders characters unseen during training.
Controllable Multi-Line Text: Flexible multi-line synthesis with line-level control.
Data Efficient: Uses a fraction of data (e.g., ~1%) compared to other methods.
