1. A face recognition apparatus, comprising: a face localizer extracting a predetermined number of feature points from a facial region extracted from an input image to be recognized; a Gabor filter unit applying a set of Gabor filters with a plurality of orientations and frequencies to each of the facial feature points in order to obtain filter responses and thereby generating a one-dimensional (1-D) vector including the filter responses of the input image to be recognized; a training data set storage storing a plurality of gabor-filtered 1-D vectors that are obtained from a plurality of training images; and a binary classifier generating a binary determination criterion using the plurality of gabor-filtered 1-D vectors stored in the training data set storage, applying the binary determination criterion to the gabor-filtered 1-D vector of the input image to be recognized, and selectively determining whether the facial region extracted from the input image to be recognized belongs to a specific person or does not belong to the specific person based on the application of the binary determination criterion, wherein the binary classifier separates the plurality of gabor-filtered 1-D vectors into one of a first class in which it is determined that a facial image belongs to a specific person and into a second class in which it is determined that a facial image does not belong to the specific person.
