摘要：Photogram met ry ha s been introduced as an alternative to dire ct measurements to obtai n facial distances for a varie ty of anthr opomet ric applications. We apply photogrammet ry to assist in the screening of chil dre n for Fetal Alcohol Syndrome (FAS). We have developed a stereo - photogrammet ric image acquisition platform t o obtai n digital photographs of 6 to 7 year - old child ren, and image processing al gori thms to extract the eye features required for FAS screening from these photographs. Images are calibrated usi ng t he Direct Linear Transform. Eye features are extracted by e xa mi ning peak and valley m aps to locate the eyes and extract the iris contour, and applying a genetic a lgorit hm t o ma tch cubic spli ne s to eye contours
