Learning RDBNs for Activity Recognition
Cristina Manfredotti · 2010
Informally, activity recognition refers to the identification of an activity involving one or more objects across time. Activities often involve multiple objects, and the relation (or interaction) between them is of predominant importance for recognizing their activity. Our approach to activity recognition of multiple interacting objects is based on a model composed of: (1) a transition part that models the dynamic aspects and allows to predict the state and (2) a relational part that models the interaction between objects.
