The invention provides an image capture system, apparatus and method for capturing a biometric image in high ambient light environments. Reflections from ambient light can introduce unwanted environmental pattern noise that can interfere with extracting information from a captured biometric image. The invention performs attenuation of ambient light without requiring employment of shielding to prevent ambient light from reflecting off of a surface being imaged. As a result, the invention can be deployed into environments with varied indoor or outdoor lighting characteristics.

System for capturing a biometric image in high ambient light environments

The apparatus represents a device having one or two sensors for capturing a single image or two images having the subject's eyes, and processor(s) in a housing with the one or two sensors and/or in a computer system which receives the single image or two images. Such processor(s) determine a head tilt angle between a virtual line extending between the two eyes of the subject in accordance with a predefined features associated with the eyes and a dimension characterizing zero head tilt in the single image or two images, segment left and right iris images, and rotate the segmented left and right iris images in accordance with the angle to substantially remove head tilt when present. The apparatus may also determine head tilt using predefined features associated with a single eye in the image. The resulting iris image(s) are utilized for enrollment or identification.

Apparatus and method for two eye imaging for iris identification

A system for animal identification includes: an image capture apparatus for obtaining an image of an eye of an animal including a pupil region and an iris region; and a template generation apparatus. The template generation apparatus is for: extracting a set of pixel data from the image, the set of pixel data representing an upper region of interest of the iris region above the pupil region and a lower region of interest of the iris region below the pupil region, the upper region of interest and the lower region of interest have parallel side boundaries that are spaced apart a distance that is substantially independent of a degree of dilation of the pupil region; and transforming the set of pixel data representing the upper region of interest and the lower region of interest into a template of the upper region of interest and the lower region of interest.
