Itsapplications include change identification between images, image fusion, object recognition, and image mosaic. In this paper, in addition to introducing the concepts of image registration, we have collected and classified different researches, as well as definition of the research approach thereof. Moreover, thevarious aspects of image registration have been evaluated through four different tests. This paper could pave the way for researchers in the field of image processing as and it has been tried to includeall aspects of this field of study herein.
