WebCross-correlation: It is used to identify a cell inside an structure. As an example, you have the image of a small piece of a city and an image of the whole city. With cross-correlation you can determine where that small picture is located inside the whole picture of the city. Saying it more simple, it "scans" until it finds a match.
