MotionSight: Boosting Fine-Grained Motion Understanding in Multimodal LLMs

ICLR 2026poster

Despite advancements in Multimodal Large Language Models (MLLMs), their proficiency in fine-grained video motion understanding remains critically limited. They often lack inter-frame differencing and tend to average or ignore subtle visual cues. Furthermore, while visual prompting has shown potentia…

OpenVid-1M: A Large-Scale High-Quality Dataset for Text-to-video Generation

ICLR 2025poster

Text-to-video (T2V) generation has recently garnered significant attention thanks to the large multi-modality model Sora. However, T2V generation still faces two important challenges: 1) Lacking a precise open sourced high-quality dataset. The previously popular video datasets, e.g.WebVid-10M and Pa…

UltraHR-100K: Enhancing UHR Image Synthesis with A Large-Scale High-Quality Dataset

NeurIPS 2025poster

Ultra-high-resolution (UHR) text-to-image (T2I) generation has seen notable progress. However, two key challenges remain : 1) the absence of a large-scale high-quality UHR T2I dataset, and (2) the neglect of tailored training strategies for fine-grained detail synthesis in UHR scenarios. To tackle t…
