Improved greedy snake model for detecting accurate pupil contour

Accurate pupil contour detection is vital for iris-based biometric systems. In this paper, a new algorithm for detecting precise pupil contour is proposed. An improved greedy snake model is presented, wherein new external energy function is designed. This external energy is extracted based on the an...
