Abstract Nowadays, action recognition is widely applied in many fields.
However, action is hard to define by single modality information. The difference
between image recognition and action recognition is that action recognition
needs more modality information to depict one action, such as the appearance,
the motion and the dynamic information. Due to the state of action evolves with
the change of time, motion information must be considered when representing an
action. Most of current methods define an action by spatial information and
motion information. There are two key elements of current action recognition
methods: spatial information achieved by sampling sparsely on… More >
