This research introduces SA-OcrPaint, a training-free framework designed to improve the accuracy of visual text within images generated by two-stage text-to-image models. The framework enhances text layout and corrects misspellings, demonstrating substantial quantitative improvements in OCR-based metrics on both a new challenging benchmark (LenCom-EVAL) and established datasets like MARIO-EVAL.
Key insights
- A training-free framework can significantly enhance text-to-image models' ability to accurately render visual text without requiring extensive retraining.
- Optimizing text layout using simulated annealing to minimize bounding box overlap is crucial for improving legibility in generated images.
- Recursive in-painting guided by OCR feedback effectively corrects misspellings and blurriness in generated visual text, especially for complex or rare sequences.
