Researchers have developed TongGuOCR, a novel OCR framework designed to improve the transcription of Chinese historical documents. This system addresses challenges like complex layouts and rare characters by employing a layout-aware preprocessing module and a token-augmented recognition module. The token augmentation includes character-level vocabulary expansion for rare glyphs and spatial displacement tokens to guide the reading order. Experiments on benchmark datasets demonstrate that TongGuOCR surpasses existing OCR models and multimodal large language models, achieving significant improvements in accuracy and error reduction. AI
