采用Gabor-Hough变换的自适应滤波人眼定位
Eye Location Based on Adaptive Filter Using Gabor-Hough Transform
摘要
Abstract
Eye location is the first step of the face recognition. Traditional eye location methods need to cut the face,and the situation is single. For complex background or leaned images,the methods have low accu-racy and poor tolerance. In this paper,the improved adaptive filter is combined with the traditional positio-ning methods. Firstly,the original image is transformed with the Gabor Transform to find the sag regions. In these regions the pupil is detected with edge pixel vector improved Hough Transform to gain the first ref-erence coordinates. The filter is trained and rotated for two times to get three coherent filters,then the im-age goes though the coherent filters to find three target coordinates. Finally,the best target which has the minimum error is chosen as the final target. Compared with the traditional methods,the new method avoids the weakness of aimless computation and has the general applicability of the traditional method. At the same time,the adaptive filter makes the mean error reduce to 0. 040 4,and computing pressure reduce to 1/5. The method has better robustness for different illumination, uneven illumination, different counte-nance,complex background images and leaned head images,thus avoiding the situation of locating no tar-gets and wrong targets with single method.关键词
