Multi-Polarization Information Fusion for Object Contour Display in Passive Millimeter-Wave and Terahertz Security Imaging

Abstract

Passive millimeter-wave/terahertz (PMMW/PTW) imaging has been widely developed for personal security screening in recent years. In PMMW/PTW images, object contours are an important feature for object detection and recognition. In this paper, a physical-based contour display method by fusing multi-polarization information is proposed. The polarization characteristics are investigated by analyzing the physical principle of contour edge generation. The feasibility of displaying contour edges is verified through simulation experiments for a typical security check scene. The presented method can enhance the contrast between concealed objects and human body, and then label contour edges.
