ReFocus: Visual Editing as a Chain of Thought for Structured Image Understanding

ICML 2025poster

Structured image understanding, such as interpreting tables and charts, requires strategically refocusing across various structures and texts within an image, forming a reasoning sequence to arrive at the final answer. However, current multimodal large language models (LLMs) lack this multihop selec…

TrOCR: Transformer-Based Optical Character Recognition with Pre-trained Models

AAAI 2023technical

Text recognition is a long-standing research problem for document digitalization. Existing approaches are usually built based on CNN for image understanding and RNN for char-level text generation. In addition, another language model is usually needed to improve the overall accuracy as a post-process…

XFUND: A Benchmark Dataset for Multilingual Visually Rich Form Understanding

ACL 2022findings

Multimodal pre-training with text, layout, and image has achieved SOTA performance for visually rich document understanding tasks recently, which demonstrates the great potential for joint learning across different modalities. However, the existed research work has focused only on the English domain…

LayoutLMv2: Multi-modal Pre-training for Visually-rich Document Understanding

ACL 2021long

Pre-training of text and layout has proved effective in a variety of visually-rich document understanding tasks due to its effective model architecture and the advantage of large-scale unlabeled scanned/digital-born documents. We propose LayoutLMv2 architecture with new pre-training tasks to model t…

TAP: Text-Aware Pre-Training for Text-VQA and Text-Caption

CVPR 2021poster

In this paper, we propose Text-Aware Pre-training (TAP) for Text-VQA and Text-Caption tasks. These two tasks aim at reading and understanding scene text in images for question answering and image caption generation, respectively. In contrast to the conventional vision-language pre-training that fail…
