Decomposed Attention Fusion in MLLMs for Training-free Video Reasoning Segmentation

ICLR 2026poster

Multimodal large language models (MLLMs) demonstrate strong video understanding by attending to visual tokens relevant to instructions. To exploit this for training-free localization, we cast video reasoning segmentation as video QA and extract attention maps via rollout. Since raw maps are too nois…

Multi-Granular Spatio-Temporal Token Merging for Training-Free Acceleration of Video LLMs

ICCV 2025poster

Video large language models (LLMs) achieve strong video understanding by leveraging a large number of spatio-temporal tokens, but suffer from quadratic computational scaling with token count. To address this, we propose a training-free spatio-temporal token merging method, named STTM. Our key insigh…

MiniROAD: Minimal RNN Framework for Online Action Detection

ICCV 2023poster

Online Action Detection (OAD) is the task of identifying actions in streaming videos without access to future frames. Much effort has been devoted to effectively capturing long-range dependencies, with transformers receiving the spotlight for their ability to capture long-range temporal structures.…

VISOLO: Grid-Based Space-Time Aggregation for Efficient Online Video Instance Segmentation

CVPR 2022oral

For online video instance segmentation (VIS), fully utilizing the information from previous frames in an efficient manner is essential for real-time applications. Most previous methods follow a two-stage approach requiring additional computations such as RPN and RoIAlign, and do not fully exploit th…
