OmniView-Space: Reinforcing Spatial Reasoning via Multi-Perspective Spatial Mapping

Xudong Li, Mengdan Zhang, Peixian Chen +7

Spatial intelligence remains a persistent challenge for Multimodal Large Language Models (MLLMs), as it requires coherent spatial scene representations beyond basic object recognit…

Wavelet-based Frame Selection by Detecting Semantic Boundary for Long Video Understanding

Wang Chen, Yuhui Zeng, Yongdong Luo +5

Frame selection is crucial due to high frame redundancy and limited context windows when applying Large Vision-Language Models (LVLMs) to long videos. Current methods typically sel…

Zooming from Context to Cue: Hierarchical Preference Optimization for Multi-Image MLLMs

Xudong Li, Mengdan Zhang, Peixian Chen +8

Multi-modal Large Language Models (MLLMs) excel at single-image tasks but struggle with multi-image understanding due to cross-modal misalignment, leading to hallucinations (contex…

Long-VITA: Scaling Large Multi-modal Models to 1 Million Tokens with Leading Short-Context Accuracy

Yunhang Shen, Chaoyou Fu, Shaoqi Dong +14

We introduce Long-VITA, a simple yet effective large multi-modal model for long-context visual-language understanding tasks. It is adept at concurrently processing and analyzing mo…

Scale Contrastive Learning with Selective Attentions for Blind Image Quality Assessment

Runze Hu, Zihao Huang, Xudong Li +3

Human visual perception naturally evaluates image quality across multiple scales, a hierarchical process that existing blind image quality assessment (BIQA) algorithms struggle to…
