EgoExoLearn: A Dataset for Bridging Asynchronous Ego- and Exo-centric View of Procedural Activities in Real World

1 code implementation24 Mar 2024 Yifei HUANG, Guo Chen, Jilan Xu, Mingfang Zhang, Lijin Yang, Baoqi Pei, Hongjie Zhang, Lu Dong, Yali Wang, LiMin Wang, Yu Qiao

Along with the videos we record high-quality gaze data and provide detailed multimodal annotations, formulating a playground for modeling the human ability to bridge asynchronous procedural actions from different viewpoints.

MoVQA: A Benchmark of Versatile Question-Answering for Long-Form Movie Understanding

no code implementations8 Dec 2023 Hongjie Zhang, Yi Liu, Lu Dong, Yifei HUANG, Zhen-Hua Ling, Yali Wang, LiMin Wang, Yu Qiao

While several long-form VideoQA datasets have been introduced, the length of both videos used to curate questions and sub-clips of clues leveraged to answer those questions have not yet reached the criteria for genuine long-form video understanding.

Language-guided Human Motion Synthesis with Atomic Actions

1 code implementation18 Aug 2023 Yuanhao Zhai, Mingzhen Huang, Tianyu Luan, Lu Dong, Ifeoma Nwogu, Siwei Lyu, David Doermann, Junsong Yuan

In this paper, we propose ATOM (ATomic mOtion Modeling) to mitigate this problem, by decomposing actions into atomic actions, and employing a curriculum learning strategy to learn atomic action composition.
