1. A face illumination normalization method, comprising:

  • (a) acquiring a digital image including data corresponding to a face that appears to be illuminated unevenly;

    (b) applying one or more uneven illumination classifier programs to the face data;

    (c) identifying the face data as corresponding to said face within the digital image;

    (d) determining an uneven illumination condition for the face also as a result of the applying of the one or more uneven illumination classifier programs;

    (e) correcting the uneven illumination condition of the face based on the determining to thereby generate a corrected face image appearing to have more uniform illumination; and

    (f) electronically storing, transmitting, applying a face recognition program to, editing, or displaying the corrected face image, or combinations thereof.
