Abstract
Investigates energy function minimization process for eye feature extraction based on deformable template. The minimization process is divided into three steps, which emphasizes on local properties of energy terms. The iris is located firstly. Then the eye boundaries are adjusted. Finally, all energy terms are activated to tune the eye template. Each step needs not to be split to some sub-steps. Empirical comparison with other minimization processes shows the superiority of the proposed process in terms of both efficiency and accuracy.
