Face Recogniton Algorithm Based on 2D-DWT and FLD

On the basis of weighted 2D Discrete Wavelet Transform(2D-DWT) and Fisher Linear Discriminant(FLD),this paper presents a face recognition algorithm.It decomposes face image into level two by wavelet db2,extracts image features using FLD method for the decomposed image.The extracted features are recognized by nearest neighbor classifier.On the basis of ORL face database,experimental results show the algorithm has high recognition rate.
