- W2375669867 abstract "For the purpose of localizing iris precisely and quickly, a new and fast iris location algorithm using gray projection and Hough transform is presented. Based on the gray distribution features of eye image, this paper improved the commonly used coarse location method. Firstly, threshold segmentation using gray projection is applied to locate the pupil. Then it enhances the iris edge image to extract the edge information. After that, it utilized the prior knowledge of pupil circle centre and radii to locate the iris edge accurately by using the predigested Hough transform. Experimental results show that this algorithm is easy to realize, reduces the blindness of the search process, and improves the speed." @default.
