TAR: Temporal Anchor-Constrained Reasoning for Video Temporal Grounding

Chaohong Guo, Xun Mo, Yongwei Nie +3

Video Temporal Grounding (VTG) aims to localize specific video segments corresponding to natural language queries. While recent Large Vision-Language Models (LVLMs) employ Reinforc…

Invert4TVG: A Temporal Video Grounding Framework with Inversion Tasks Preserving Action Understanding Ability

Zhaoyu Chen, Hongnan Lin, Yongwei Nie +4

Temporal Video Grounding (TVG) aims to localize video segments corresponding to a given textual query, which often describes human actions. However, we observe that current methods…

Beyond Inference Intervention: Identity-Decoupled Diffusion for Face Anonymization

Haoxin Yang, Yihong Lin, Jingdan Kang +4

Face anonymization aims to conceal identity information while preserving non-identity attributes. Mainstream diffusion models rely on inference-time interventions such as negative…

RecDreamer: Consistent Text-to-3D Generation via Uniform Score Distillation

Chenxi Zheng, Yihong Lin, Bangzhen Liu +3

Current text-to-3D generation methods based on score distillation often suffer from geometric inconsistencies, leading to repeated patterns across different poses of 3D assets. Thi…
