GlyphPrinter: Region-Grouped Direct Preference Optimization for Glyph-Accurate Visual Text Rendering

Q: What products could be built from this research?

Now is the ideal time because demand for automated visual content is surging with the rise of social media, e-commerce, and AI-driven design tools, yet existing solutions struggle with text accuracy. Advances in preference optimization and increased availability of annotated datasets make this approach feasible, while market pressure for faster, cheaper content creation creates a clear need for more reliable text rendering.

Q: What are the practical use cases?

A SaaS tool for e-commerce platforms that automatically generates product images with stylized, glyph-accurate text overlays for promotions, such as sale banners or personalized messages, ensuring text is both attractive and readable across different languages and devices.

METHOD

Full abstract

Generating accurate glyphs for visual text rendering is essential yet challenging. Existing methods typically enhance text rendering by training on a large amount of high-quality scene text images, but the limited coverage of glyph variations and excessive stylization often compromise glyph accuracy, especially for complex or out-of-domain characters. Some methods leverage reinforcement learning to alleviate this issue, yet their reward models usually depend on text recognition systems that are insensitive to fine-grained glyph errors, so images with incorrect glyphs may still receive high rewards. Inspired by Direct Preference Optimization (DPO), we propose GlyphPrinter, a preference-based text rendering method that eliminates reliance on explicit reward models. However, the standard DPO objective only models overall preference between two samples, which is insufficient for visual text rendering where glyph errors typically occur in localized regions. To address this issue, we construct the GlyphCorrector dataset with region-level glyph preference annotations and propose Region-Grouped DPO (R-GDPO), a region-based objective that optimizes inter- and intra-sample preferences over annotated regions, substantially enhancing glyph accuracy. Furthermore, we introduce Regional Reward Guidance, an inference strategy that samples from an optimal distribution with controllable glyph accuracy. Extensive experiments demonstrate that the proposed GlyphPrinter outperforms existing methods in glyph accuracy while maintaining a favorable balance between stylization and precision.

RESULT

ScienceToStartup currently rates this 4.0/10 on the public viability pass. Extensive experiments demonstrate that the proposed GlyphPrinter outperforms existing methods in glyph accuracy while maintaining a favorable balance between stylization and precision.
