1. A method for recognizing a face on an image, comprising: a) recording a plurality of images respectively having an object to be recognized; b) applying an image classification algorithm for measuring similarity of two images and determining identification thereof, that is, estimating similarity of the image to be tested and the registered image by using the algorithm, and determining the class of the image to be tested; c) learning a method for generating a binary classifier for identifying the object of the designated class from other classes, and using the binary classifier so as to classify the input image; and d) recognizing an input image that is available for classification according to a plurality of registered images by applying the binary classifier and combining the classified results.
