1. A face registration system using a SVM comprising: an image input unit for inputting face images of users to be registered in the registration system; a face and eye region extraction unit for extracting face and eye regions from each face image inputted to the image input unit; a control unit for classifying the face images of users into training and tuning face images and forming a set of features representing chromosomes of each face image of training and tuning images; and a SVM classifier for iteratively measuring fitness value of the set of features of each chromosome of the training image using GA (Generic Algorithms) to select the set of features most suitable to be a feature vector of a corresponding user requesting face authentication and extracting a feature vector from the face image of other users corresponding to the selected set of features, thereby comparing two vectors to determine a result of face authentication.
