One key step in preventing terrorism and crime is to determine whether people are carrying concealed weapons in prohibited environments. We are developing a system, called Weapon Grabber, which provides the means for detection and recognition of weapons hidden underneath a person's clothing. There are several critical scenarios in which CWD can help a great deal in taking preventive measures, enhancing security, and/or complementing other security systems. Most importantly, the CWD technology can provide a great deal of safety to police officers by determining if a suspect is carrying a hidden weapon. Weapon Grabber incorporates new image and video processing algorithms using the multiple millimeter wave (MMW) and Infrared (IR) sensors, enabling operator-assisted or automatic weapon detection systems. The CWD technology has traditionally used image processing (registration and fusion) to extract usable information from the images taken from different sensors taking advantage of still images under ideal conditions. In contrast, we are developing new techniques of video registration and fusion technology, in which multiple video sequences, taken from various types of sensors across space and time will be fused to maximize the degree of detection to enhance the accuracy of weapon detection.
