  • Patent number: 11144756
    Abstract: Described herein are methods and systems of distinguishing between a glance event and an eye closure event in a subject monitoring system. A method includes capturing a number of images of the subject's face including at least one eye of the subject over a period of time; processing the images to determine a closure state of at least one eye; detecting potential eye closure events in which the closure state of at least one eye is determined to be in a closed state; for corresponding detected potential eye closure event, determining a head pitch angle of the subject and classifying the potential eye closure event as a glance event if a head pitch angle of the subject is detected to change by an angle greater than a predetermined head pitch angle and otherwise classifying the potential eye closure event as an eye closure event.

  • Patent number: 10521683
    Abstract: A system and method are provided for actively illuminating and capturing images of an object, such as a driver of a vehicle to reduce glare. The system includes a video imaging camera orientated to generate images of the subject object (e.g., eye(s)) in successive video frames. The system also includes first and second light sources operable to illuminate the object one at a time. The system further includes a processor for processing the image by performing a functional operation to reduce glare in the image. The system may remove glare caused by the illuminators and by external energy sources.

  • Patent number: 8165347
    Abstract: The invention relates to the application area of camera-based head and eye tracking systems. The performance of such systems typically suffers when eye glasses are worn, as the frames of the glasses interfere with the tracking of the facial features utilized by the system. This invention describes how the appearance of the glasses can be utilized by such a tracking system, not only eliminating the interference of the glasses with the tracking but also aiding the tracking of the facial features. The invention utilizes a shape model of the glasses which can be tracked by a specialized tracker to derive 3D pose information.
