Human action recognition using dimensionality reduction and support vector machine

Abstract

The paper is devoted to the problem of recognizing human actions in videos recorded in the optical range of wavelengths. An approach proposed in this paper consists in the detection of a moving person on a video sequence with the subsequent size normalization, generation of subsequences and dimensionality reduction using the principal component analysis technique. The classification of human actions is carried out using a support vector machine classifier. Experimental studies performed on the Weizmann dataset allowed us to determine the best values of the method parameters. The results showed that with a small number of action classes, high classification accuracy can be achieved.
