| Shrnutí: | Computer vision technology is becoming a research focus in the field of basketball. Despite the abundance of datasets centered on basketball games, there remains a significant gap in the availability of a large-scale, multi-subject, and fine-grained dataset for the recognition of basketball actions in real-world sports scenarios, particularly for amateur players. Such datasets are crucial for advancing the application of computer vision tasks in the real world. To address this gap, we deployed multi-view cameras in a civilian basketball gym, constructed a real basketball data acquisition platform, and acquired a challenging multi-subject video dataset, named MultiSubjects. The MultiSubjects v1.0 dataset features a variety of ages, body types, attire, genders, and basketball actions, providing researchers with a high-quality and diverse resource of basketball action data. We collected a total of 1,000 distinct subjects from video data between September and December 2023, classified and labeled three basic basketball actions, and assigned a unique identity ID to each subject, provided a total of 6,144 video clips, 436,460 frames, and labeled 6,144 instances of actions with clear temporal boundaries using 436,460 human body bounding boxes. Additionally, complete frame-wise skeleton keypoint coordinates for the entire action are provided. We used some representative video action recognition algorithms as well as skeleton-based action recognition algorithms on the MultiSubjects v1.0 dataset and analyzed the results. The results confirm that the quality of our dataset surpasses that of popular video action recognition datasets, it also presents that skeleton-based action recognition remains a challenging task.
