FACE FEATURE POINT DETECTION DEVICE AND PROGRAM

摘要

Detecting with good precision an eye inside corner position and an eye outside corner position as face feature points even when the eye inside corner and/or the eye outside corner portions are obscured by noise. First eyelid profile modeling is performed with a Bezier curve expressed by a fixed control point P 3 indicating an eye inside corner first position detected in an image, a fixed control point P 4 indicating an eye outside corner first position, a control point P 1 corresponding to an upper eyelid position candidate (first parameter), and a control point P 2 corresponding to a lower eyelid position candidate (second parameter). Then in a second eyelid profile model with fixed P 1 and P 2 of the first eyelid profile model having the highest fitting evaluation value » to the eyelid profile in the image, the values of a control point P 3 indicating an eye inside corner position candidate (third parameter) and a control point P 4 indicating an eye outside corner candidate (fourth parameter) at a maximum of a fitting evaluation value » when changing the values of the control point P 3 and control point P 4 are determined as an eye inside corner second position and an eye outside corner second position, respectively.
