We propose a method to create a video descriptor composed of three main steps: Computation of displacement vectors between frames with VSBMA, histogram representation of these vectors, and orientation tensor generation from the histogram. It is a promising approach for human action recognition since it is a simple method with low computational cost which achieves comparable results with state-of-the-art techniques. ER -
