METHOD FOR ILLUMINATION NORMALIZATION ON A DIGITAL IMAGE FOR PERFORMING FACE RECOGNITION |
摘要 |
<p>A method for performing illumination normalization on a digital image, comprising : a) receiving an input image; b) determining, for each pixel, a first adaptation factor F1(p); c) applying to said input image a first adaptive non linear function using said first adaptation factor F1(p) to get a first modified image (Ila1); d) determining, for each pixel, a second adaptation factor F2(p) using the first modified image (Ila1); e) applying to the resulting image (Ila1) of step c a second adaptive non linear function using said second adaptation factor F2(p) to get a second modified image (IIa2); f) applying to the resulting image (Ila2) of step e a Difference of Gaussians (DoG) filter to get a normalized image (In). A face recognition system and a method for performing face recognition are also provided.</p> |
