pupil and iris segmentation system in digital images. The present invention is a pupil and iris segmentation process to be used within an iris recognition system within the context of identifying individuals. The iris segmentation system according to the present invention provides for the replacement of matrix operations by vector operations, and for this purpose the system locates the centers and radii of the pupil and iris to allow separation of relevant and sufficient biometric information. for the identification of the individual comprising the steps of: - image smoothing - in which a digital noise elimination filter is applied; - Binarization - in which the representation of the eye image is transformed into black or white pixels, eliminating the intermediate values; - determination of the center and radius of the pupil; and - determining the center and radius of the iris.
