The synergistic combination of laser radar and infrared sensors segments the man made objects out of cluttered back-ground and enhances the the distinguishing features of those objects. The gradients extracted from laser radar and infrared sensors provide the basic tools. The nearest neighbors' patterns aide in determining the actual location, size and boundary of the targets. The combination of processed laser radar and infrared data through multiple masking presents information that is not visible in either of the sensors by itself. This paper will discuss the gradient based methods of target segmentation and enhancement and present some characteristic results.
