Claim One:
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 region of the image to provide a linear array of row averages stored as a first signature, wherein the region includes a predetermined arrangement of pixels within the image; rotating the region relative to the image to provide a rotated image; creating an average for each one of a plurality of rows of pixels in the rotated image to provide a linear array of rotated row averages stored as a second signature; translating the region relative to the image to provide a translated image; creating an average for each one of a plurality of rows of pixels in the translated 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.
