Keywords:Activity Description

Events of single object is not sufficient for describing highly semantic activities.
We propose a description method for person activity recognition, especially abnormal activity detection.
We discussed the need of appropriete granularity of both spatial and temporal event descriptions.
Using 3 examples from Sports activities, we evaluated the effectiveness of our description method.
