Abstract

In this paper, we describe the Toshiba event detection system for TRECVID surveillance event detection task [1]. Our system consists of four components: (1) a flexible and robust change detection based on non-parametric background modeling, (2) a human detection that extends and outperforms HOG (Histogram of Oriented Gradient) human detection, (3) a human tracking with simple linear estimation and color histogram matching, and (4) an event detection for three TRECVID required events (E05, E19, and E20) based on change detection and human tracking. Our current system has just adopted a simple version of each component and requires further refinement.
