FIS-OT: Feature-Induced Optimal Transport for Unsupervised Action Segmentation
Linxiang Peng, Xinyao Qin, Jinhan Li +2
Unsupervised action segmentation is a challenging task. It involves finding action categories and boundaries in videos without labels. Existing Optimal Transport (OT) methods use g…
MASQ: Mask-Aware Spatiotemporal Quantization for Unsupervised Skeleton Action Segmentation
Xinyao Qin, Linxiang Peng, Youbao Ye +2
Unsupervised skeleton-based temporal action segmentation is a crucial task for understanding human behavior in long untrimmed sequences. Recent approaches often rely on discrete qu…
Entity-Aware Sequence Transduction for Player-Centric Ball Action Spotting
Ruifeng Wang, Di Yang, Jiangtao Wang
Player-centric ball action spotting requires temporally precise event detection together with actor attribution in crowded, partially observed multi-agent sports videos. Existing D…
From General Actions to Domain-Specific Monitoring: Prior-Adaptive Transfer for Skeleton-Based Action Recognition
Hao Wang, Di Yang, Jiangtao Wang
Skeleton-based action recognition models have recently shown strong performance on large-scale benchmarks with general actions. However, directly transferring them to domain-specif…
Virtual Biopsy for Intracranial Tumors Diagnosis on MRI
Xinzhe Luo, Shuai Shao, Yan Wang +3
Deep intracranial tumors situated in eloquent brain regions controlling vital functions present critical diagnostic challenges. Clinical practice has shifted toward stereotactic bi…
ReBA-Pred-Net: Weakly-Supervised Regional Brain Age Prediction on MRI
Shuai Shao, Yan Wang, Shu Jiang +6
Brain age has become a prominent biomarker of brain health. Yet most prior work targets whole brain age (WBA), a coarse paradigm that struggles to support tasks such as disease cha…
PD-Diag-Net: Clinical-Priors guided Network on Brain MRI for Auxiliary Diagnosis of Parkinson's Disease
Shuai Shao, Yan Wang, Shu Jiang +5
Parkinson's disease (PD) is a common neurodegenerative disorder that severely diminishes patients' quality of life. Its global prevalence has increased markedly in recent decades.…
