The figure depicts the simulated progression of the image through an iris recognition algorithm: the eye of the subject, the blurred captured image with the lens and phase mask presented in the paper, the segmentation of the iris boundaries, the normalization of the segmented iris image, and finally the actual binary iris code from the algorithm in the paper. The captured image assumes that the eye is located at the best-focus plane of the lens.
