- W2375991587 abstract "Based on the current methods of iris localization,a fast localization approach using square geometrical diagram was proposed.The concrete procedures are specified as follows: addressing the characteristics of the pupil generally masked by the small interferences such as eyelash and eyelid,the median filtering is applied to deal with the original iris images in order to eliminate the disturbance of the bright speckles and tiny edges;the defined square geometrical diagram is employed to determine the circle center of the pupil so as to implement the initial localization;finally the sector-searching way fixed with some direction and the edge detection operator of Canny is involved in the precise iris localization.The experiment demonstrates that the scheme not only exhibits the favorable adaptivity for capturing the radius of the image,but also reduces the localization time effectively." @default.
