A Texture-based Method for Detecting Moving Objects

The detection of moving objects from video frames plays an important and often very critical role in different kinds of machine vision applications including human detection and tracking, traffic monitoring, humanmachine interfaces and military applications, since it usually is one of the first phases in a system architecture. A common way to detect moving objects is background subtraction. In background subtraction, moving objects are detected by comparing each video frame against an existing model of the scene background. In this paper, we propose a novel block-based algorithm for background subtraction. The algorithm is based on the Local Binary Pattern (LBP) texture measure. Each image block is modelled as a group of weighted adaptive LBP histograms. The algorithm operates in real-time under the assumption of a stationary camera with fixed focal length. It can adapt to inherent changes in scene background and can also handle multimodal backgrounds.
