A Novel Preprocessing Method for Illumination-Variant Color Face Image

摘要：

　　This paper proposes a novel preprocessing method for the illumination-variant color face image.The proposed method aims to balance the luminosity and the color variation by color adjustment, bilateral filtering, and luminosity adjustment of sub image, which were required form input image by row-column transform and form which the output image was required by row column inverse transform.The experimental results show that this preprocessing method can help to improve the segmentation precision and has good speed and robustness.
