This paper proposes a palmprint feature extraction method based on low frequency distribution. Firstly, it does the Fourier transform to palmprint, and extracts the power distribution of the frequency domain image as palmprint feature. Then it makes a feature match. The experiment results prove that this method is simple to realize, and has advantages of handy operation, fast responding velocity and high recognition rate.
