Abstract

For the robust recognition of noisy face images, this paper proposed an improved fast neighborhood component analysis (FNCA) method by introducing a spatially smooth regularizer (FNCA-SSR). The SSR can penalize large differences between adjacent pixels by enforcing local spatially smoothness, and makes FNCA-SSR model robust to Gaussian and pepper-salt noises in face image. Experimental results on the ORL and FERET face data sets show that, for the recognition of noisy face images, FNCA-SSR is very robust and can achieve much higher recognition accuracy than FNCA and other subspace methods.
