Efficient Gabor Phase Based Illumination Invariant for Face Recognition

Abstract EN

This paper presents a novel Gabor phase based illumination invariant extraction method aiming at eliminating the effect of varying illumination on face recognition.

Firstly, It normalizes varying illumination on face images, which can reduce the effect of varying illumination to some extent.

Secondly, a set of 2D real Gabor wavelet with different directions is used for image transformation, and multiple Gabor coefficients are combined into one whole in considering spectrum and phase.

Lastly, the illumination invariant is obtained by extracting the phase feature from the combined coefficients.

Experimental results on the Yale B and the CMU PIE face database show that our method obtained a significant improvement over other related methods for face recognition under large illumination variation condition.
