In this paper we present a new method for synthesizing illumination invariant images for face recognition. The method classifies the appearance caused by illumination according to four properties: diffuse reflection, specular reflection, attached shadow and cast shadow. Among these properties, the shadow and the specular reflection dynamically change the appearance. Classification from a single image is difficult because shadows and specular reflection depend on the facial shape and the light source. Therefore, we use a generic face model defined by a few basis images for classification. For each pixel in the original image, we design a filter based on the classification result, which is used to compute the Self Quotient Image (SQI). At each location the SQI contains the ratio of the albedo at that pixel and a locally smoothed value of the albedo. Through experimental results we show the effectiveness of this method for face identification on a public database and on a database used in practice, using only a single image for each individual reference. |
