Biometric identification is one of the technologies used for automated personal identification.Iris recognition is biometric-based identification method which are more reliable and accurate authentication system.This paper present a simple and efficient method based on localized energy-based active contour model to segment iris from human eye image.First we segment the rough iris image and it is then redefined in the second level segmentation to produce better result.This proposed method is tested with the eye images obtained from CASIA database.The performance of the method is quantitatively evaluated by calculating the similarity measures Jaccard (J) and Dice (D).Experimental results show that the proposed method provides better segmentation result compared to the expert segmented images. .
