Face feature extraction is the core of recognition task,which directly impact on classification velocity and face recognition ability. The main contributions of this work are listed as follows： ()Face feature extraction algorithm based on Gabor transform is introduced. Compared with Fourier transform，Gabor transform is proved to be better in face feature extraction.And then，A fast algorithm of Gabor Transform is introduced. (2) According to the disadvantages of Gabor wavelet,This paper introduced LBP operator, the operator can overcome the f aults of Gabor wavelet transform effectively . Also it introduced the principle and realization process how to extract features face in detailed, and the selection of parameters of Gabor filter are detailed instructions. (3) For the problem to the face feature vector high dimension in Gabor and LBP extraction ,this paper used the LPP and PCA dimension reduction algorithm reduced the dimension. (4) In the final face feature extraction ,By calculating the distance of the feature vector to look the similarity between the image to inquire and each image in
