Reason with Thumbnails, Answer with Focus: An Efficient and Effective Paradigm for Multimodal Grounded Visual Reasoning

ICML 2026poster

To enhance the interpretability of multimodal large language models' outputs, recent efforts explored Grounded Visual Reasoning (GVR), in which the model is trained to select relevant image regions before answering the question. However, the multi-round ``ground-then-answer'' and reasoning nature of…

Dolphin: Document Image Parsing via Heterogeneous Anchor Prompting

ACL 2025finding

Document image parsing is challenging due to its complexly intertwined elements such as text paragraphs, figures, formulas, and tables. Current approaches either assemble specialized expert models or directly generate page-level content autoregressively, facing integration overhead, efficiency bottl…

ParGo: Bridging Vision-Language with Partial and Global Views

AAAI 2025technical

This work presents ParGo, a novel Partial-Global projector designed to connect the vision and language modalities for Multimodal Large Language Models (MLLMs). Unlike previous works that rely on global attention-based projectors, our ParGo bridges the representation gap between the separately pre-tr…

WildDoc: How Far Are We from Achieving Comprehensive and Robust Document Understanding in the Wild?

EMNLP 2025

The rapid advancements in Multimodal Large Language Models (MLLMs) have significantly enhanced capabilities in Document Understanding. However, prevailing benchmarks like DocVQA and ChartQA predominantly comprise scanned or digital documents, inadequately reflecting the intricate challenges posed by

Human Guided Cross-Modal Reasoning with Semantic Attention Learning for Visual Question Answering

ICASSP 2024accepted

One of the major difficulties in the Visual Question Answering (VQA) task of real-world images is the long-tailed distribution of concepts which makes the model vulnerable to negative linguistic biases. To imitate human learning and reasoning, researchers have designed reasoning models, which, howev…

TabPedia: Towards Comprehensive Visual Table Understanding with Concept Synergy

NeurIPS 2024poster

Tables contain factual and quantitative data accompanied by various structures and contents that pose challenges for machine comprehension. Previous methods generally design task-specific architectures and objectives for individual tasks, resulting in modal isolation and intricate workflows. In this…

Supervised Raw Video Denoising With a Benchmark Dataset on Dynamic Scenes

CVPR 2020poster

In recent years, the supervised learning strategy for real noisy image denoising has been emerging and has achieved promising results. In contrast, realistic noise removal for raw noisy videos is rarely studied due to the lack of noisy-clean pairs for dynamic scenes. Clean video frames for dynamic s…
