ROBOT APPARATUS, FACE RECOGNITION METHOD, AND FACE RECOGNITION APPARATUS

摘要

A robot includes a face extraction unit for extracting a feature of a face contained in an image picked up by a CCD camera and a face recognition unit for recognizing a face according to the face extraction result obtained by the face extraction unit. The face extraction unit is composed of a Gabor filter for filtering an image by using a plurality of filters having direction selectivity and different frequency components. The face recognition unit is composed of a support vector machine for mapping the face extraction result onto a non-linear space and obtaining a hyperplane for separation in the space, thereby distinguishing face from non-face. The robot can recognize a user face in a dynamically changing environment within a predetermined time.
