Abstract: A facial recognition method and apparatus are provided. The face recognizing apparatus divides an input face image into a plurality of regions, generates a feature vector consisting of real values for each region of the input face image, and generates an image feature vector using the generated feature vectors for each region. In addition, the face recognizing apparatus performs a search for finding whose face image the input face image is by using the image feature vector.
