abstract
Image fusion of registered images of night scenery that are obtained from cameras tuned to different bandwidths will be a significant component of future night vision devices. In this article, we describe a new algorithm for such multispectral image fusion. The algorithm performs gray scale image fusion using a method based on principal components. The monochrome fused image is then colored by means of a suitable pseudocoloring technique to produce the fused color output image. The approach can be easily used for any number of bandwidths. We have provided examples where the algorithm was used to fuse a intensified low light visible image with another image obtained from a single FLIR camera. The algorithm may be implemented readily in hardware for use in night vision devices, as an important aid to surveillance and navigation in total darkness.
