    • A method and an apparatus for illumination normalization of a face image are provided to increase the recognition ration of a face recognition system by removing a partial shadow with the illumination. An upper bit plane adopting a bit plane as many as the number designated in a bit plane obtained from a pixel value of a facial image is obtained(S410). A blurring mask that expresses the shadow discontinuity by the lighting of the facial image is determined by using the upper bit plane(S420). A lighting-estimated image is outputted by performing the blurring filtering of the blurring mask to the facial image(S430), and the lighting-normalized image in which the illumination is removed from the facial image is obtained by using only the illumination estimation image and the facial image(S440).

    • A method and an apparatus for illumination normalization are provided to remove a shadow having discontinuity similar to object's properties effectively by using two discontinuous measuring methods and use a new transfer function when connecting the two discontinuous measuring methods, thereby removing a shadow without deteriorating object's properties. A weight calculating unit(130) calculates each weight with regard to each pixel by using a predetermined transfer function. An illumination estimating unit(140) performs a predetermined convolution operation as much as set repetition times by receiving each weight to measure illumination. An illumination normalization unit(150) normalizes illumination by removing the estimated illumination from an input image.
