Modeling Human Activities

چکیده
The ability to recognize the actions of our conspecifics constitutes one of our fundamental cognitive abilities. The ability to understand, and to react to, human actions is thus crucial for cognitive systems of the future. Actions are complex entities, possessing several representations linguistic, visual, cognitive, and motor. The key to understanding actions is to understand the relationship between these different spaces. In this paper, we study the visual representation of actions and find parallels to natural language processing by representing actions as Probabilistic Context Free Grammars. We also provide a review of previous work done in the field of human action recognition.
