Abstract

In this paper, we present an approach to action description based on temporal pyramid histograms. Bag of features is a widely used action recognition framework based on local features, for example spatio-temporal feature points. Although it outperforms other approaches on several public datasets, sequencing information is ignored. Instead of only calculating the occurrence of code words, we also encode their temporal layout in this work. The proposed temporal pyramid histograms descriptor is a set of histogram atoms generated from the original video clip and its subsequences. To classify actions based on the temporal pyramid histograms descriptor, we design a function to calculate the weights of the histogram atoms according to the corresponding sequence lengths. We test the descriptor using nearest neighbour for classification. Experimental results show that, in comparison to the state-of-the-art, our description approach improves action recognition accuracy.
