Face Recognition Based on Fourier Scale Invariant FeaturesCHEN Mianshu

A face recognition method based on discrete Fourier invariant features is presented. Starting from continuous Fourier transform, the properties of continuous Fourier transform are discussed, and the paper gives the properties of discrete Fourier transform. Then according to the properties of discrete Fourier transform, it deduces the discrete Fourier invariant features that are employed on facial image recognition. The experiment results show that the face recognition methods based on discrete Fourier invariantfeatures proposed have a good ability of recognition for the translation, scale and rotation-on-the-plane variant face images.
