Any Information Is Just Worth One Single Screenshot: Unifying Search With Visualized Information Retrieval

ACL 2025long

With the popularity of multimodal techniques, it receives growing interests to acquire useful information in visual forms. In this work, we formally define an emerging IR paradigm called Visualized Information Retrieval, or Vis-IR, where multimodal information, such as texts, images, tables and char…

MLVU: Benchmarking Multi-task Long Video Understanding

CVPR 2025poster

The evaluation of Long Video Understanding (LVU) performance poses an important but challenging research problem. Despite previous efforts, the existing video understanding benchmarks are severely constrained by several issues, especially the insufficient lengths of videos, a lack of diversity in vi…

MomentSeeker: A Task-Oriented Benchmark For Long-Video Moment Retrieval

NeurIPS 2025poster

Accurately locating key moments within long videos is crucial for solving long video understanding (LVU) tasks. However, existing benchmarks are either severely limited in terms of video length and task diversity, or they focus solely on the end-to-end LVU performance, making them inappropriate for…

Unveiling the Ignorance of MLLMs: Seeing Clearly, Answering Incorrectly

CVPR 2025poster

**M**ultimodal **L**arge **L**anguage **M**odels (MLLMs) have displayed remarkable performance in multimodal tasks, particularly in visual comprehension. However, we reveal that MLLMs often generate incorrect answers even when they understand the visual content. To this end, we manually construct a…

Video-XL: Extra-Long Vision Language Model for Hour-Scale Video Understanding

CVPR 2025poster

Long video understanding poses a significant challenge for current Multi-modal Large Language Models (MLLMs). Notably, the MLLMs are constrained by their limited context lengths and the substantial costs while processing long videos. Although several existing methods attempt to reduce visual tokens,…

AnimateDiff: Animate Your Personalized Text-to-Image Diffusion Models without Specific Tuning

ICLR 2024spotlight

With the advance of text-to-image (T2I) diffusion models (e.g., Stable Diffusion) and corresponding personalization techniques such as DreamBooth and LoRA, everyone can manifest their imagination into high-quality images at an affordable cost. However, adding motion dynamics to existing high-quality…

Self-Supervised Multi-Modal Knowledge Graph Contrastive Hashing for Cross-Modal Search

AAAI 2024technical

Deep cross-modal hashing technology provides an effective and efficient cross-modal unified representation learning solution for cross-modal search. However, the existing methods neglect the implicit fine-grained multimodal knowledge relations between these modalities such as when the image contains…
