ABSTRACT:
Two or more images captured from digital cameras record an image of spectacle frames on a subject. The image is analyzed using automated image-processing techniques to identify the relation of specific points of interest on the frame to the location of each of the subject's eyes allowing the optical center of the lens to be placed in the correct location in the frames.
