Retinoblastoma is a pediatric ocular cancer typically indicated by leukocoria (white-eye pupillary reflex). Early detection of leukocoria can improve health outcomes when it indicates disease, and it can be easily seen in recreational photographs. As part of a system for automatic leukocoria detection, we propose an image processing algorithm for detecting the exact location and radius of the smallest circle containing the iris in an eye image. Our algorithms use both median filters and
