Towards Balanced Alignment: Modal-Enhanced Semantic Modeling for Video Moment Retrieval

1 code implementation19 Dec 2023 Zhihang Liu, Jun Li, Hongtao Xie, Pandeng Li, Jiannan Ge, Sun-Ao Liu, Guoqing Jin

In this paper, we introduce Modal-Enhanced Semantic Modeling (MESM), a novel framework for more balanced alignment through enhancing features at two levels.

Dual-Stream Knowledge-Preserving Hashing for Unsupervised Video Retrieval

no code implementations12 Oct 2023 Pandeng Li, Hongtao Xie, Jiannan Ge, Lei Zhang, Shaobo Min, Yongdong Zhang

Hence, we address this problem by decomposing video information into reconstruction-dependent and semantic-dependent information, which disentangles the semantic extraction from reconstruction constraint.

Balanced Classification: A Unified Framework for Long-Tailed Object Detection

1 code implementation4 Aug 2023 Tianhao Qi, Hongtao Xie, Pandeng Li, Jiannan Ge, Yongdong Zhang

In this paper, we contend that the learning bias originates from two factors: 1) the unequal competition arising from the imbalanced distribution of foreground categories, and 2) the lack of sample diversity in tail categories.

MomentDiff: Generative Video Moment Retrieval from Random to Real

1 code implementation NeurIPS 2023 Pandeng Li, Chen-Wei Xie, Hongtao Xie, Liming Zhao, Lei Zhang, Yun Zheng, Deli Zhao, Yongdong Zhang

Video moment retrieval pursues an efficient and generalized solution to identify the specific temporal segments within an untrimmed video that correspond to a given language description.

Progressive Spatio-Temporal Prototype Matching for Text-Video Retrieval

1 code implementation ICCV 2023 Pandeng Li, Chen-Wei Xie, Liming Zhao, Hongtao Xie, Jiannan Ge, Yun Zheng, Deli Zhao, Yongdong Zhang

In the event-sentence prototype matching phase, we design a temporal prototype generation mechanism to associate intra-frame objects and interact inter-frame temporal relations.
