Abstract

A method for indexing a digital image is disclosed. The image is divided into sections, the average pixel intensity of each section is determined, the average pixel intensity of each section is compared to the average pixel intensity of at least one other section, and a numerical identifier or signature is established. Also disclosed is a method of searching for an image on a computer. The signature for the image to be searched for is established, which includes allowing for a specified tolerance as sections of the image are compared. The signature of the image to be searched for is then compared to signatures of other images. An image is a match if the signatures are identical, within a specified tolerance.
