Masked Autoencoders for Spatial-Temporal Relationship in Video-Based Group Activity Recognition

Group Activity Recognition (GAR) is a challenging problem involving several intricacies. The core of GAR lies in delving into spatiotemporal features to generate appropriate scene representations. Previous methods, however, either feature a complex framework requiring individual action labels or nee...
