Abstract
A system for one dimensional segmentation of an iris of an eye into a map of the iris and classification of the map into unaffected areas and affected areas. Also, the system may provide for regular shape fitting of the areas for normalization and identifying the unaffected areas as symmetric segments. Further, the system may assign weights to the unaffected areas and the affected areas of the map of the iris and an enrolled map of an iris and their corresponding bins for matching purposes.
Claims7
A method of iris capture, comprising:
- one dimensional segmentation of an iris into a map of the iris;
- and
- classification of the map into unaffected areas and affected areas;
- assigning weights to the unaffected areas and the affected areas of the map of the iris and an enrolled map of an iris;
- and
- wherein:
- higher weights are attributed to unaffected areas of the map of the iris and the enrolled map of an iris;
- lower weights are attributed to affected areas of the map of the iris and the enrolled map of an iris;
- and
- weights between the higher weights and the lower weights are attributed to unaffected and affected areas of the map of the iris and the enrolled map of an iris.
