[2024/03]Part of EgoExoLearn raw annotations released.[2024/03]EgoExoLearn paper released.[2024/03]Annotation and code for the cross-view association and cross-view referenced skill assessment benchmarks are released.[2024/03]EgoExoLearn code and data initially released.
We propose EgoExoLearn, a dataset that emulates the human demonstration following process, in which individuals record egocentric videos as they execute tasks guided by exocentric-view demonstration videos. Focusing on the potential applications in daily assistance and professional support, EgoExoLearn contains egocentric and demonstration video data spanning 120 hours captured in daily life scenarios and specialized laboratories. 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.
Please visit each subfolder for code and annotations. More updates coming soon.
We design benchmarks of 1) cross-view association, 2) cross-view action understanding (action segmentation, action ancitipation, action planning), 3) cross-view referenced skill assessment, and 4) cross-view referenced video captioning. Each benchmark is meticulously defined, annotated, and supported by baseline implementations. In addition, we pioneeringly explore the role of gaze in these tasks. We hope our dataset can provide resources for future work for bridging asynchronous procedural actions in ego- and exo-centric perspectives, thereby inspiring the design of AI agents adept at learning from real-world human demonstrations and mapping the procedural actions into robot-centric views.
