Abstract

In this paper, we evaluate and compare different feature detection and feature description methods for part-based approaches in human action recognition. Different methods have been proposed in the literature for both feature detection of space-time interest points and description of local video patches. It is however unclear which method performs better in the field of human action recognition. We compare, in the feature detection section, Dollar's method, Laptev's method, a bank of 3D-Gabor filters and a method based on Space-Time Differences of Gaussians. We also compare and evaluate different descriptors such as Gradient, HOG-HOF, 3D SIFT and an enhanced version of LBP-TOP. We show the combination of Dollar's detection method and the improved LBP-TOP descriptor to be computationally efficient and to reach the best recognition accuracy on the KTH database.
