    摘要: Disclosed is a method for determining a gaze direction of a user (5) by employing a neural network (220) operating on the basis of image data of an image of a face of the user (5). The neural network (220) detects an ellipse (20) representing an outer border of an iris (17) of the user's eye (15) and outputs a first vector (31), a second vector (32) and a respective first and second probability (pi, pz) representing the probability that the first vector (31) or the second vector (32) is the gaze direction Further disclosed are an apparatus configured to perform such method and a vehicle comprising such apparatus.

    摘要: A computing device prompts a user to place the user's hand next to a facial region of the user and obtains an image depicting the facial region and a finger of the user. The computing device measures a diameter of an iris in the facial region and measures a width of finger region located between two knuckles on the finger depicted in the image. The computing device estimates a ring size of the finger based on an actual iris diameter, the measured iris diameter, and/or the measured finger region width. The computing device outputs the estimated ring size.

    摘要: A method and a system for tracking and quantifying visual attention on a computing device are disclosed. The method comprises acquiring photo frames of a user when the user is looking at a computing device; detecting a user's face within each frame and both eyes of the user within the detected user's face, providing a plurality of 3D eye and face images; feeding the plurality of 3D eye and face images to a first machine learning algorithm comprising a set of sub-algorithms, each one of said set of sub-algorithms transforming the right eye into a left eye by performing a specular reflection through a vertical line that intercepts the center of a frontal lens of the camera, providing a new set of transformed images; and estimating a user's attention by feeding the new set of transformed images to a second machine learning algorithm, the latter reverting said specular reflection.

    摘要: Systems and methods pertaining to iris recognition are disclosed. A system is disclosed comprising an iris imager configured to acquire an iris image, and a processor configured to receive a first plurality of iris images from the iris imager, generate a first plurality of iris codes corresponding to the first plurality of iris images, generate a distribution metric corresponding to an iris cell location, generate a first composite iris code using the distribution metric, and generate a first match value using the first composite iris code and a first stored iris code.
