Knowledge-based face recognition using neural networks

In this paper, we propose a method for facial feature extraction and recognition algorithm based on neural networks. First we separate the face part from the captured image based on the fact that the face image is located in the center of an input image and the background is relatively uniform. Then we obtain 4 normalized features from the extracted face image. For face recognition, we use the backpropagation technique of the neural networks. The proposed knowledge-based technique recognizes 14 persons correctly.
