First Claim
Patent Images
1. A computer system for biometric iris matching, comprising:
- a processor;
memory coupled to the processor, the memory comprising instructions configured to cause the computer system to;
receive at least one input image of an eye;
generate one or more edge maps corresponding to each of the at least one input image;
segment a pupil area in each of the at least one input image;
segment an iris area from a sclera area in each of the at least one input image; and
synthesize an artificial pupil on the at least one input image within the segmented pupil area.

Abstract
A method and apparatus for biometric iris matching comprising pre-processing an input image capturing one or more eyes to produce one or more rectified iris images, coding the one or more rectified iris images into one or more multiresolution iris codes and matching the one or more multiresolution iris code with a set of stored multiresolution iris codes to determine whether a match exists.

12. A computer system for biometric iris matching, comprising:
-
a processor; and memory comprising instructions configured to cause the computer system to; receive at least one input image of an eye; estimate an angle of tilt of the eye in the at least one input image with respect to a camera that captured the image; and correct corneal distortion based on the estimated angle of tilt. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method for biometric iris matching, implemented on a computer system, the method comprising:
-
receiving at least one input image of an eye; segmenting a pupil area in an eye detected in at least one input image; selecting a pupil contour based on one or more of a best fitting circle and a best inscribed circle; and segmenting an iris area from a sclera area in each of the one or more eyes in the input image. - View Dependent Claims (19, 20)
