Abstract :
In this paper, an improved temporal template called posture energy image (PEI) is proposed for human action representation and analysis. The template was computed from silhouette sequences which were generated from tracking and cutting moving regions in video clips. Comparing with other temporal templates, PEI is more intelligent: the time duration of PEI could be adjusted automatically. Experiments were performed on the CASIA databases and the results showed that the proposed template is an effective representation of human actions, especially for actions with whole-body movement.
