Abstract
Violent detection from video is a hot topic which has wide application. The aim of this paper is to design a novel feature descriptors called motion gradient location and orientation histogram (MoGLOH), which encode not only the local appearance but also explicitly models local motion. Our proposed MoGLOH is composed of two part of information. The first part is the gradient location and orientation histogram (GLOH) describing the spatial appearance, and the second part is an aggregated histogram of optical flow with a log-polar location grid named Optical Flow Orientation Histogram (OFOH) which indicate the movement of feature point. To eliminate the feature noise, the non-parametric Kernel Density Estimation (KDE) is employed on the MoGLOH descriptor. The theoretical analysis demonstrates the proposed algorithm performs robustly and favorably.
