NASs contain a variety of information about human actions and are robust against variations due to noises, occlusions, changes in scales, and a range of structural changes since they are concatenations of features at multiple spatial-temporal scales. The results suggest that NASs can be used as the basic encoding units of human actions and activities and may hold the key to the understanding of human ability of action recognition.
