Eyelid shape estimation using eye pose measurement
11538280 · 2022-12-27 · ·

Systems and methods for eyelid shape estimation are disclosed. In one aspect, after receiving an eye image of an eye (e.g., from an image capture device), an eye pose of the eye in the eye image is determined. From the eye pose, an eyelid shape (of an upper eyelid or a lower eyelid) can be estimated using an eyelid shape mapping model. The eyelid shape mapping model relates the eye pose and the eyelid shape. In another aspect, the eyelid shape mapping model is learned (e.g., using a neural network).

Image processing method and apparatus

An image processing method includes receiving an image frame, detecting a face region of a user in the image frame, aligning a plurality of preset feature points in a plurality of feature portions included in the face region, performing a first check on a result of the aligning based on a first region corresponding to a combination of the feature portions, performing a second check on the result of the aligning based on a second region corresponding to an individual feature portion of the feature portions, redetecting a face region based on a determination of a failure in passing at least one of the first check or the second check, and outputting information on the face region based on a determination of a success in passing the first check and the second check.

METHOD AND DEVICE FOR BIOMETRIC IDENTIFICATION AND/OR AUTHENTICATION
20220391483 · 2022-12-08 ·

A method for biometric identification or authentication is described. An image of a body region is obtained. A truth map for said body region is obtained, said truth map associating, with each portion of a set of portions of said image of a body region, a probability that said portion belongs to a true body region. The image of the body region is then compared with a group of reference biometric data using the truth map. Finally, the identification or authentication of said body region is validated or invalidated in response to said comparison.

PILOT SAFETY SYSTEM WITH CONTEXT-SENSITIVE SCAN PATTERN MONITORING AND ALERTING

An aircraft-based pilot safety system (PSS) includes cameras or other gaze sensors fixed at an aircraft pilot and configured to capture an image stream focused on the pilot's eyes. The gaze sensors continually assess the gaze direction of the pilot (e.g., toward a display, instrument panel, and/or indicator within the cockpit that the pilot is currently looking at or focusing on) and thereby can establish when the pilot is executing a scan pattern and if that scan pattern is nominal for the current flight context by comparing the scan pattern to context-specific reference scan patterns. If, for example, the pilot's gaze deviates from where it should be (e.g., as determined by the current flight segment) or the current scan pattern is interrupted, the system may prompt the pilot to redirect their gaze or resume the scan pattern.
