Abstract:
1. A robot apparatus that operates autonomously, comprising: image input means for inputting a face image; facial feature extraction means for extracting features of the face image using a set of high frequency Gabor filters, a set of mid-frequency Gabor filters and a set of low frequency Gabor filters, the Gabor filters in each set having respective orientation selectivities that vary by predetermined increments; and face discrimination means for discriminating a particular face from other faces and including a support vector machine operable to perform non-linear mapping of said extracted features by using a kernel function, and obtaining a hyperplane that separates the non-linearly mapped features in a feature space; wherein said face discrimination means performs learning and when said face discrimination means outputs an erroneous recognition result after learning, said face image is used for learning again.
