Abstract：This paper proposed a visual perception and edge preserving illumination invariant face recognition method,which on one hand employs a visual perception based image gradient to replace the image special gradient to make the method be more consistent with the human visual system,and on the other hand,proposes a novel diffusion equation to overcome the edge sharpening problem.The novel method can preserve the image edge and meanwhile can eliminate the halo effect and spot effect to some extent.Experimental results on EYaleB and CMU PIE databases show that the proposed method outperforms other compared methods,which illustrates the effectiveness of the proposed method.
