- W2383198924 abstract "This paper proposed an efficient method for face recognition.It developed a pretreatment strategy that could deal with image gradation to restrain upper sensitivity of PCA from the change of illumination in an image.The training and testing samples were selected with random sequences from the face database,processed with power transformation and a Butterworth low-pass filter,and finally processed with the PCA algorithm.The experimental results based on the ORL database show that the achieved recognition rate with the proper power transformation values is 96.70%.Therefore,the proposed algorithm can have higher accuracy of recognition than the traditional ones." @default.
