A method and apparatus for identifying images having different spatial characteristics divides the image into a predetermined number of image elements, determines whether each of the image elements is relatively light or relatively dark and assigns a white designation or a black designation to each image element as a result of this determination. The number of white designated and black designated image elements are counted, as are the number of like designated image elements adjacent to each image element. The counts thus obtained are compared with corresponding counts resulting from known images, and the image is identified when a match within a predetermined tolerance is found.

A method for automatically identifying an image, comprising the steps of: reading said image with a scanning device and segmenting said image into a plurality of image elements; providing a signal representative of a predetermined characteristic of each image element; assigning one of first and second designations to each image element in response to the value of the portion of the signal representative of that element and providing a first or second value signal representative of the designation of each image element; automatically determining from said first and second value signals the number of image elements disposed in a predetermined spatial relationship about preselected ones of said image elements assigned said first designation that have a designation predeterminedly related to said first designation and providing a signal representative thereof; automatically determining from said first and second value signals the number of image elements disposed in a predetermined spatial relationship about preselected ones of said image elements assigned said second designation that have a designation predeterminedly related to said second designation and providing a signal representative thereof; automatically determining from said number representative signals one of a plurality of predetermined values for each of said preselected image elements representative of the designation of each preselected element and the number of said predeterminedly related image elements disposed thereabout and providing a count signal representative of the number of preselected image elements having each of said predetermined values; and utilizing the count signal to identify the image.
