ROBOT APPARATUS, FACE RECOGNITION METHOD, AND FACE RECOGNITION APPARATUS

摘要

PROBLEM TO BE SOLVED: To allow a robot to recognize faces of users within a predetermined time under a dynamically changing environment. SOLUTION: The robot includes a face extracting section for extracting features of a face included in an image captured by a CCD camera, and a face recognition section for recognizing the face based on a result of face extraction by the face extracting section. The face extracting section is implemented by Gabor filters that filter images using a plurality of filters that have orientation selectivity and that have different frequency components, and the face recognition section is composed of a support vector machine that maps the result of face recognition to a non-linear space once and that obtains a hyperplane that separates in that space to discriminate a face from a non-face.
