Face image recognition by 2-dimensional discrete Walsh transform and multi-layer neural network
This report describes face image recognition by 2-dimensional discrete Walsh transform and multi-layer neural networks. Neural network (NN) is one of the powerful tools for pattern recognition. In the previous researches of face image recognition by NN, the gray levels on each pixel of the face image have been used for input data to NN. However, because the face image has usually too many pixels, a variety of approaches have been required to reduce the number of the input data. In this research. 2-dimensional discrete Walsh transform is used for reduction of input. data and the recognition is done by multi-layer neural networks. Finally; the validity of our method is varified.
