METHOD OF SEARCHING FOR PARAMETERIZED CONTOURS FOR COMPARING IRISES |
| 摘要 |
A method for detecting outlines for iris comparison comprises a step of selecting N candidate outlines of circular form by applying a circle search technique to an image of edges of an iris. It also comprises a step of optimizing the form and the position of the N candidate outlines, the optimized candidate outlines being determined by using parametric models, a set of parameters being determined for each candidate outline by minimizing a quantity of energy E(C). The method also comprises a step of selecting the best optimized candidate outline. |
