AN EYE LOCALIZATION FILTER

摘要

A system for fast eye localization based on a filter utilizes the relatively high horizontal-contrast density of the eye region to determine eye positions in a greyscale image of a human face. The system comprises a camera for scanning an individual and a processor for performing the required filtering. The filtering includes a horizontal-contrast computation filter, a horizontalcontrast density determination filter, facial geometry reasoning and eye position determination and works with various eye shapes, face orientations and other factors such as eye glasses or even when the eyes are closed.
