Abstract


One of the most crucial social issues is assuring the safety of crowded public places like e.g. airports. One aspect of this problem is the detection of potentially dangerous objects hidden under person’s clothing. There are various solutions to find different suspicious elements: from simple metal detectors up to X-ray scanners. Moreover, some of available solutions are harmful to human beings. Therefore, there is a great potential in using multispectral surveillance imagers in security systems and that is why we investigate the possibilities of concealed object detection by screening people using non-invasive cameras working in various spectral ranges.
