Preprints

EFS pipeline for event partitioning, anchor localization, and global refinement2026

arXiv preprint · Equal contribution

Event-Anchored Frame Selection for Effective Long-Video Understanding

Wang Chen*, Yongdong Luo*, Yuhui Zeng, Luojun Lin, Tianyu Xie, Fei Chao, Rongrong Ji, Xiawu Zheng

Partitions video into coherent events, localizes a query-relevant anchor in each event, and applies adaptive MMR for global refinement across coverage, relevance, and diversity.

Real-time interactive face beautification through target-score interpolation across an aesthetic hyperplane2024

SSRN preprint

Real-Time Interactive Face Beautification

Luojun Lin, Wang Chen, Peizhen Chen, Xiawu Zheng, Lianwen Jin

Constructs an aesthetics hyperplane and interpolates directly in latent space for real-time, target-score-controlled editing with identity preservation.

SocialOmni benchmark overview, task design, and omni-model performance2026
