Eyes Location Based on Phase Congruency Images
The paper focuses on eyes location under nonlinear illuminations. Considered phase congruency is insensitive to illumination, a novel algorithm of eyes location based on phase congruency images is presented. Firstly, the eyes are located roughly by integral projection. Secondly, Hough transform is used to determine the center of eyes after the images are transformed to phase congruency images. The results of experiment indicate that the algorithm is excellent in locating human eyes under nonlinear illuminations.
