Machine Learning Model for Group Activity Recognition Based on Discriminative Interaction Contextual Relationship

<div>A schematic overview for group activity recognition considering contextual interaction information. (a) Group activity recognition is usually difficult to discriminate based on the visual appearance of only an individual one. (b) This framework considers interaction context information between the focal person and people nearby for group activity recognition.</div>
