Abstract
An example embodiment includes: a determination unit that, based on an image including an eye of a recognition subject, determines whether or not a colored contact lens is worn; and a matching unit that, when it is determined by the determination unit that the colored contact lens is worn, performs matching of the iris by using a feature amount extracted from a region excluding a predetermined range including an outer circumference of the iris out of a region of the iris included in the image.
Claims7
An iris recognition system comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- determine whether or not a colored contact lens is worn based on an image including an eye of a recognition subject;
- when having determined that the colored contact lens is worn, perform a predetermined process and acquire an additional image including the eye after having performed the predetermined process;
- extract a feature amount of an iris of the recognition subject by calculating a difference between the image including an eye of the recognition subject and the additional image;
- and
- perform matching of the extracted feature amount of the iris of the recognition subject against a feature amount of an iris of a previously registered person, for authenticating the recognition subject.
An information processing method performed by a computer and comprising:
- determining whether or not a colored contact lens is worn based on an image including an eye of a recognition subject;
- when having determined that the colored contact lens is worn, performing a predetermined process and acquire an additional image including the eye after having performed the predetermined process;
- extracting a feature amount of an iris of the recognition subject by calculating a difference between the image including an eye of the recognition subject and the additional image;
- and
- performing matching of the extracted feature amount of the iris of the recognition subject against a feature amount of an iris of a previously registered person, for authenticating the recognition subject.
A non-transitory computer-readable medium storing a program executable by a processor to perform a method comprising:
- determining whether or not a colored contact lens is worn based on an image including an eye of a recognition subject;
- when having determined that the colored contact lens is worn, performing a predetermined process and acquire an additional image including the eye after having performed the predetermined process;
- extracting a feature amount of an iris of the recognition subject by calculating a difference between the image including an eye of the recognition subject and the additional image;
- and
- performing matching of the extracted feature amount of the iris of the recognition subject against a feature amount of an iris of a previously registered person, for authenticating the recognition subject.
