Digital image fusion is the technology of data fusion mainly study the images is the different patterns of images of the same scene sensors to the same number of sensors or images acquired at different times the same scene for a number of synthetic images images process. The first introduced digital image integration definition, the current development and research hot, and then discussed the integration of images of the rules, methods and steps. Three integration algorithms and procedures given that the PCA algorithms, pyramid image integration algorithms and algorithms based on wavelets change procedures discussed in the final image integration technology in the military, medical imaging and remote sensing, monitoring and control applications.
