Abstract: Methods and apparatus for illuminating a biometric aspect, such as periocular region features or iris features, with multiple illumination configurations to create multiple illumination channels for computer analysis are disclosed. Multiple illumination channels may be used for quality assurance by comparing the actual illumination channel property of a given image to the illumination channel that was activated for image capture. Images captured at the multiple illumination channels can also be used in biometric authentication by providing additional information for comparison to a stored template generated from images taken at multiple illumination channels during enrollment. Biometric authentication using a quality assurance process may be resistant to attempts to bypass biometric authentication.

Abstract: Methods and apparatus for using polarized light (e.g., infrared (IR) light) to improve eye-related functions such as iris recognition. An eye camera system includes one or more IR cameras that capture images of the user's eyes that are processed to perform iris recognition, gaze tracking, or other functions. At least one polarizing element may be located in the path of the light which is used to capture images of the user's eye. The user's eye may be illuminated by IR light emitted by one or more LEDs. At least one of the LEDs may be an LED with a polarizing filter. Instead or in addition, at least one polarizer may be located at the eye camera sensor, in the eye camera optics, or as or in an additional optical element located on the light path between the eye camera and the user's eye.

Abstract: Methods and apparatus for stray light mitigation in optical systems that include two or more illumination sources (e.g., point light sources such as light-emitting diodes (LEDs)) that illuminate an object to be imaged, and a camera configured to capture images of light from the point light sources reflected by the object when illuminated. To mitigate “occlusions” or artifacts caused by, for example, stray light or reflections of the illumination sources off of other components of the system, multiple images of the object are captured with different groups of the illumination sources enabled. The captured images can then be processed and merged to generate an output image with the occlusions or artifacts caused by stray light or reflections mitigated or eliminated.

Abstract: Methods and apparatus for fabricating light-emitting diodes (LEDs) that include polarizing or wavefront-altering optical components are described in which additional optical components are added to the LED package to filter or modify the polarization of the emitted photons. Packaged LEDs that include polarizing or wavefront-altering optical components are also described. The packaged LEDs may emit infrared light that is polarized or otherwise altered by the optical components added during the fabrication process.

Abstract: Methods and apparatus for flexible illumination that improve the performance and robustness of an imaging system are described. Multiple different lighting configurations for the imaging system are pre-generated. Each lighting configuration may specify one or more aspects of lighting. A lookup table may be generated via which each pose is associated with a respective lighting configuration. A user may put on, hold, or otherwise use the device. A process may be initiated in which different lighting configurations may be selected by the controller to capture images of the user's eye, periorbital region, or face at different poses and in different conditions for use by a biometric authentication or gaze tracking process.

Abstract: The invention relates to an eye tracking device (10a; 10b; 10c) comprising a processing unit (18) and an optical system (14), which comprises a capturing unit. The optical system (14) provides a first optical path (P; P1) with a first imaging property and a second optical path (P; P2) with a second imaging property and the capturing unit (C; C1, C2) captures a first image (24a) by capturing light that has passed along the first optical path (P; P1) and a second image (24b) by capturing light that has passed along the second optical path (P; P2), so that due to the difference of the first and second imaging property the first (24a) and the second image (24b) comprise a difference related to a characteristic of at least part of the first and the second image (24b), wherein the eye tracking device (10a; 10b; 10c) is configured to determine a property of the eye (12) on the basis of at least one of the first image (24a) and the second image (24b).

Abstract: Techniques are disclosed relating to devices that support biometric authentication. In various embodiments, a device includes a biosensor configured to collect biometric data from a user. An authentication system of the device is configured to perform a user authentication based on the collected biometric data. After performance of the user authentication, the authentication system receives sensor data indicating that the user remains collocated with the device and receives a request to confirm an authentication of the user. Based on the user authentication and the received sensor data, the authentication system confirms that the user has been authenticated. In various embodiments, the authentication system is configured to receive additional sensor data indicating that the user is no longer collocated with the device and, in response to a subsequent authentication request, require the user to perform another biometric authentication using the biosensor.

Abstract: Methods for performing user authentication based on a multi-representation eye model for devices such as head-mounted display devices are disclosed. The multi-representation eye model may be generated and updated based on feature representations of an identified eye. The user authentication process may be initiated by causing an image to be captured of a current eye under a first set of conditions that may then be transformed into a current feature representation. The current feature representation may be applied to the multi-representation eye model to determine whether the current eye is a match for the identified eye.

Abstract: Methods and apparatus for biometric authentication in which two or more biometric features or aspects are captured and analyzed individually or in combination to identify and authenticate a person. An imaging system captures images of a person's iris, eye, periorbital region, and/or other regions of the person's face, and two or more features from the captured images are analyzed individually or in combination to identify and authenticate the person and/or to detect attempts to spoof the biometric authentication. Embodiments may improve the performance of biometric authentication systems, and may help to reduce false positives and false negatives by the biometric authentication algorithms.
