Image recognition using singular value decomposition based on wavelet low-frequency band

This paper proposes a face recognition method using uniform eigen-space singular value decomposi- tion(SVD)based on Wavelet low-frequency band.Wavelet Transform is applied to obtain low-frequency band of facial image.By using Fourier transform,the spectrum representation of low-frequency band is obtained. Then the spectrum is projected into a uniform eigen-spaoe that is obtained from SVD of standard face image and the resultant coefficients are used as the feature of the facial image for recognition.The L_1 distance classifi- er is adopted in recognition.The experimental results show the proposed method gives higher recognition accu- racy than the uniform eigen-space SVD.
