Context Enhancement of Nighttime Surveillance by Image Fusion

In this paper, we propose a novel method of automatically combining images of a scene at different time intervals by image fusion. All the important information of the original low quality nighttime images is combined with the context from a high quality image of the daytime at the same viewpoint. The fused image contains a comprehensive description of the scene which is more useful for human visual and machine perception. Experimental results show that the proposed method is robust and effective
