This paper presents an approach to automatically register IR and millimeter wave images for concealed weapons detection application. The distortion between the two images is assumed to be a rigid body transformation and we assume that the scale factor can be calculated from the sensor parameters and the ratio of the two distances from the object to the imagers. Therefore, the pose parameters that need to be found are x-displacement and y-displacement only. Our registration procedure involves image segmentation, binary correlation and some other image processing algorithms. Experimental results indicate that the automatic registration procedure performs fairly well.
