SphereVideo: Prototype-anchored Hyperspherical Boundary for Continual AI-generated Video Detection
Fei Li, Yue Yu, Yuran Wang +3
AI-generated video (AIGV) detection aims to distinguish real videos from AI-generated ones. In practice, detectors trained on existing data often fail to generalize to newly emergi…
Uncertainty-Aware Token Importance Estimation in Spiking Transformers
Wenxuan Liu, Zecheng Hao, Tong Bu +2
Spiking transformers have shown strong potential for neuromorphic vision, yet their token processing across multiple spiking steps still introduces substantial redundancy and infer…
SPAN: Continuous Modeling of Suspicion Progression for Temporal Intention Localization
Xinyi Hu, Yuran Wang, Ruixu Zhang +3
Temporal Intention Localization (TIL) is crucial for video surveillance, focusing on identifying varying levels of suspicious intentions to improve security monitoring. However, ex…
Beyond the Individual: Introducing Group Intention Forecasting with SHOT Dataset
Ruixu Zhang, Yuran Wang, Xinyi Hu +5
Intention recognition has traditionally focused on individual intentions, overlooking the complexities of collective intentions in group settings. To address this limitation, we in…
Devil is in Details: Locality-Aware 3D Abdominal CT Volume Generation for Self-Supervised Organ Segmentation
Yuran Wang, Zhijing Wan, Yansheng Qiu +1
In the realm of medical image analysis, self-supervised learning (SSL) techniques have emerged to alleviate labeling demands, while still facing the challenge of training data scar…
Anomize: Better Open Vocabulary Video Anomaly Detection
Fei Li, Wenxuan Liu, Jingjing Chen +4
Open Vocabulary Video Anomaly Detection (OVVAD) seeks to detect and classify both base and novel anomalies. However, existing methods face two specific challenges related to novel…
