Wavelet-based FLD for face recognition
Wan-Su Lee, H.J. Lee, J.H. Chung · 2002
We introduce, in this paper, a face recognition method which employs the wavelet-based FLD (Fisher Linear Discriminant). This paper deals with accuracy as well as facial speed for face recognition. An image of 128/spl times/128 is decomposed to sub-images with 16/spl times/16 resolution by wavelet transform. Then two sub-images of low and mid-range frequency bands are trained and used to recognize faces. Experimental results show that the proposed algorithm is faster maintaining the recognition rate of original FLD method. Our experiments, the computational time is reduced by factor of about 6.
