4-Step Face Authentication Algorithm Based on SVM

A kind of 4-step face authentication algorithm was proposed. At first, the primitive photograph was decomposed by the wavelet transformation, extracting the low frequency part and eliminating noise. Then the images were put into the process of 2DPCA to get smaller image for the next step. Fisher linear substitution completed characteristic extractions thirdly. Finally, the support vector machine was used to realize face authentication. The experimental results obtained on the ORL face database have confirmed the validity of this algorithm.
