Iris image preprocessing algorithms were studied and had been made betterments according to their limitations and iris features.A new iris image denoising and localization algorithm were presented,which showed high speed and veracity.Finally,iris enhancement and adjustment were given.The results show that the algorithm not only is good to the speed and veracity of iris location but also robust.
