DeFacto: Counterfactual Thinking with Images for Enforcing Evidence-Grounded and Faithful Reasoning

ICML 2026poster

Recent advances in multimodal language models (MLLMs) have made thinking with images a dominant paradigm for multimodal reasoning. However, existing methods still fail to ensure evidence–answer consistency, where correct answers must be supported by correct visual evidence. To address this issue, we…

OURO: A Self-Bootstrapped Framework for Enhancing Multimodal Scene Understanding

ICCV 2025poster

Multimodal large models have made significant progress, yet fine-grained understanding of complex scenes remains a challenge. High-quality, large-scale vision-language datasets are essential for addressing this issue. However, existing methods often rely on labor-intensive manual annotations or clos…

Boosting Supervised Dehazing Methods via Bi-Level Patch Reweighting

ECCV 2022poster

"Natural images can suffer from non-uniform haze distributions in different regions. However, this important fact is hardly considered in existing supervised dehazing methods, in which all training patches are accounted for equally in the loss design. These supervised methods may fail in making prom…
