  • 摘要:Problem statement: Iris segmentation is one of the most important steps in iris recognition system and determines the accuracy of matching. Most segmentation methods in the literature assumed that the inner and outer boundaries of the iris were circular. Hence, they focus on determining model parameters that best fit these hypotheses. This is a source of error, since the iris boundaries were not exactly circles. Approach: In this study we proposed an accurate iris segmentation method that employs Chan-Vese active contour method to extract the iris from his surrounding structures. Results: The proposed method was implemented and tested on the challenging UBIRIS database the results indicated the efficacy of the proposed method. Conclusion: The experimental results showed that the proposed method localized the iris area probably even when the eyelids occlude same part of iris.
