Unified Structure Learning for OCR-free Document Understanding
Introduction
Researchers from Alibaba Group and the Renmin University of China have developed DocOwl 1.5, a Unified Structure Learning system, to enhance the performance of Multimodal Large Language Models (MLLMs) in understanding text-rich images.
Key Components
- H-Reducer: A vision-to-text module designed to maintain rich text information during vision-and-language feature alignment.
- Unified Structure Learning: Comprising structure-aware parsing tasks and multi-grained text localization tasks across five domains: document, webpage, table, chart, and natural image. It helps MLLMs understand text-rich images more efficiently.
- Two-stage Training: Enhances basic text recognition and structure parsing abilities, making the model more efficient for downstream document understanding.
Performance
DocOwl 1.5 outperforms other models on ten visual document understanding benchmarks, showcasing state-of-the-art OCR-free performance.
