Abstract : In this paper, we focus on the important topic of violence recognition and detection in surveillance videos. Our goal is to determine if a violence occurs in a video (recognition) and when it happens (detection). Firstly, we propose an extension of the Improved Fisher Vectors (IFV) for videos, which allows to represent a video using both local features and their spatio-temporal positions. Then, we study the popular sliding window approach for violence detection, and we re-formulate the Improved Fisher Vectors and use the summed area table data structure to speed up the approach. We present an extensive evaluation, comparison and analysis of the proposed improvements on 4 state-of-the-art datasets. We show that the proposed improvements make the violence recognition more accurate (as compared to the standard IFV, IFV with spatio-temporal grid, and other state-of-the-art methods) and make the violence detection significantly faster.
