專利摘要

An eye center localization method is proposed. The eye center localization method includes an image sketching step, a frontal face generating step, an eye center marking step and a geometric transforming step. The image sketching step is performed to sketch a face image from an image of a database. The frontal face image generating step is performed to drive a processing unit to transform a face image into a frontal face image according to a frontal face generating model. The eye center marking step is performed to drive the processing unit to mark a frontal eye center position information according to a gradient method. The geometric transforming step is performed to drive the processing unit to calculate a rotating variable between the face image and the frontal face image, and calculate an eye center position information according to the rotating variable and the frontal eye center position information. Thus, the eye center localization method of the present disclosure locates the eye center position information from a non-frontal face image.
