Image Fusion
9.1 Introduction
Image fusion is a process by which information from different images of the same scene are incorporated into a single image. Hence, we can define image fusion as the representation of visual information contained in a number of input images into a single fused image [93, 94, 95, 96, 97 and 98]. The importance of image fusion lies in the fact that each observation image contains complementary information. When this complementary information is integrated with that of another observation, an image with the maximum amount of information is obtained.
Image fusion has been used in several application areas. In remote sensing and astronomy, multi-sensor fusion is used to achieve high spatial and spectral ...
