I don't know what you mean by "best match of a given (small) image in a
larger image." If that refers to a small image that is part of a larger
one, what does it match? If "in" should have been "to" so that the
phrase reads "best match of a given (small) image to a larger image",
then there is a scaling problem that's not trivial, but depending on the
nature of the images, reducing them to the same scale might be simple
enough. It it is, you may get further ideas from Chapter 24 of Steven W.
Smith's book, "The Scientist and Engineer's Guide to Digital Signal
Processing", available on line at http://www.dspguide.com/.
