Claim One:
1. A computer-implemented method for detecting a red-eye artifact, the method comprising: receiving an image depicting a first eye and a second eye corresponding to a human face, and coordinates corresponding to a location of the first eye and the second eye in the image; calculating a distance between the first eye and the second eye using the received coordinates; obtaining a skin tone sample from the image based on the calculated distance and the received coordinates; generating a skin tone color region in a color space based on the obtained skin tone sample; classifying a pixel corresponding to the first eye as a red-eye pixel by comparing the pixel with the generated skin tone color region and a predetermined red-eye color region and by analyzing a circular correction region having a diameter based calculated distance and centered on the coordinates corresponding to the location of the first eye, wherein the act of analyzing further comprises: identifying red-eye pixels by comparing pixels in the circular correction region to the generated skin tone color region and the predetermined red-eye color region; ascertaining a center of mass of the identified red-eye pixels; and determining an approximate iris region by comparing the pixels in the circular correction region at increasing distances from the center of mass to the generated skin tone color region and an eye-white color region; and storing an indication of the classifying relative to the pixel.
