Vector Clustering of Passive Millimeter Wave Images with Linear Polarization for Concealed Object Detection
Abstract—Passive millimeter (MMW) imaging can penetrate clothing to create interpretable imagery of concealed objects. However, the image quality is often restricted by low signal to noise ratio and temperature contrast as well as low spatial resolution. In this paper, we explore a four-channel passive MMW imaging system operating in the 8 and 3 mm wavelength regimes with linear vertical and ho...
متن کاملA Passive Millimeter-wave Imager Used for Concealed Weapon Detection
An 8mm-band passive millimeter-wave imager BHU-2D has been developed by Beihang University. This imager is designed for detecting concealed weapons on human body. The imager adopts two-dimensional synthetic aperture interferometric radiometer (SAIR) technique which avoids the radiation risk to human body. Compared with scanning technique, SAIR technique could obtain images of a larger field of ...

متن کاملConcealed Weapon Detection Using Color Image Fusion
Image fusion is studied for detecting weapons or other objects hidden underneath a person’s clothing. The focus of this paper is to develop a new algorithm to fuse a color visual image and a corresponding IR image for such a concealed weapon detection application. The fused image obtained by the proposed algorithm will maintain the high resolution of the visual image, incorporate any concealed ...
متن کاملConcealed explosive detection on personnel using a wideband holographic millimeter - wave imaging system
A novel wideband millimeter-wave imaging system is presently being developed at Pacific Northwest National Laboratory (PNNL) that will allow rapid inspection of personnel for concealed explosives, handguns, or other threats. Millimeter-wavelength electromagnetic waves are effective for this application since they readily penetrate common clothing materials, while being partially reflected from ...
