1. A face recognition method comprising: creating an SVM (support vector machine) classifier through machine learning on the basis of a degree of similiarity between divided facial images; normalizing a facial image to be authenticated to a predetermined size using a center between two eyes and dividing the normalized image into more than one image in horizontal and vertical directions, respectively; extracting characteristic vectors from the divided images and creating a similarity vector based on a degree of similiarity with respect to a registered characteristic vector; and inputting the similarity vector to the SVM classifier to perform authentication.
