IRIS RECOGNITION METHOD AND APPARATUS FOR THEREOF

摘要

An iris recognition method and an apparatus for the iris recognition method are provided to detect the iris accurately and efficiently even though an eye is covered by eyebrows or an eyelid in an image of the eye. An iris recognition method includes a step of receiving an image of an eye(S100) and filtering the image with a threshold value to obtain a binary image(S105), a step of searching candidate central search regions for the pupil center using histogram information of the binary image(S110), a step of considering points belonging into the candidate central search regions in the binary image as candidate pupil center points and performing a masking operation on concentric circles obtained by varying the radius of a circle having each of the candidate pupil center points as a center point using eight pupil boundary mask templates to detect the boundary and the center point of the pupil(S115), and a step of performing a masking operation on concentric circles obtained by varying the radius of a circle having the detected center point of the pupil as a center point with six iris boundary mask templates to detect the boundary of the iris(S120).
