1. A method for creating a signature for image matching comprising: providing an image containing a plurality of pixels; creating an average for each one of a plurality of rows of pixels in a center region of the image to provide a linear array of row averages stored as a first signature; rotating the center region relative to the image to provide a rotated center image; creating an average for each one of a plurality of rows of pixels in the rotated center image to provide a linear array of rotated row averages stored as a second signature; translating the center region relative to the image to provide a translated center image; creating an average for each one of a plurality of rows of pixels in the translated center image to provide a linear array of translated row averages stored as a third signature; and determining an element-by-element row average for each signature of the image including at least the first signature, the second signature, and the third signature, and storing the element-by-element row average as a summary image signature descriptive of the image.
