Iris recognition

An iris recognition apparatus, comprising:

• processing circuitry configured to:
• obtain a plurality of iris images corresponding to a to-be-recognized object, the plurality of iris images including at least two iris images acquired from different acquisition perspectives with respect to an eye region of the to-be-recognized object;
• obtain a disparity map between the at least two iris images through a stereo matching process, the disparity map including a disparity element representing a displacement amount in a displacement direction between two respective pixel points corresponding to a target element in the eye region in the at least two iris images;
• determine, in a target iris image that is one of the at least two iris images, a pupil edge based on the displacement amount;
• determine an iris region in the target iris image based on the pupil edge;
• perform feature extraction on the iris region to obtain an iris feature;
• and
• determine an identity associated with the to-be-recognized object based on the iris feature.

A non-transitory computer-readable storage medium storing instructions, which when executed by a processor, cause the processor to perform an iris recognition method, the method comprising:

• obtaining a plurality of iris images corresponding to a to-be-recognized object, the plurality of iris images including at least two iris images acquired from different acquisition perspectives with respect to an eye region of the to-be-recognized object;
• obtaining a disparity map between the at least two iris images through a stereo matching process, the disparity map including a disparity element representing a displacement amount in a displacement direction between two respective pixel points corresponding to a target element in the eye region in the at least two iris images;
• determining, in a target iris image that is one of the at least two iris images, a pupil edge based on the displacement amount;
• determining an iris region in the target iris image based on the pupil edge;
• performing feature extraction on the iris region to obtain an iris feature;
• and
• determining an identity associated with the to-be-recognized object based on the iris feature.
