  • Patent number: 11068711
    Abstract: The present disclosure describes systems and methods for acquiring a biometric image. A biometric camera system can position a lens of a biometric camera between a pixel array of the biometric camera and an iris. The pixel array can acquire an image of the iris using light reflected from the iris and transmitted through the lens of the biometric camera. The lens can increase a pixels per iris (PPi) value of the image of the iris acquired by the pixel array, by applying optical positive distortion to the light reflected from the iris when the light is optically directed through the lens. A processor can provide a biometric image for biometric matching, by image-processing the acquired image of the iris having the increased PPi value, with an inverse function of the optical positive distortion.

The eyetracker also obtains light-intensity information expressing an estimated amount of light energy exposing the at least one eye when registering the digital image. In response to the light-intensity information, the eye-tracker determines a range of pupil sizes. The search algorithm applies the range of pupil sizes in such a manner that a detected pupil candidate must have size within the range of pupil sizes to be accepted by the search algorithm as a valid pupil of the subject.

    Abstract: The present disclosure relates to a method and apparatus for image processing, and a computer-readable storage medium. The method includes the following actions. Face recognition is performed on an image to be processed to recognize a face region in the image to be processed. Facial feature recognition points in the face region are acquired. Coordinate values of the facial feature recognition points in a coordinate system are acquired. Distances between the facial feature recognition points and angles of a coordinate axis of the coordinate system relative to lines each connecting two of the facial feature recognition points are determined according to the coordinate values. A deviation angle of the face region is determined according to the distances between the facial feature recognition points and the angles of the coordinate axis relative to the lines each connecting two of the facial feature recognition points. A retouching template corresponding to the deviation angle is acquired.

  • Patent number: 10896318
    Abstract: Occlusion of facial features may be detected and assessed in an image captured by a camera on a device. Landmark heat maps may be used to estimate the location of landmarks such as the eyes, mouth, and nose of a user's face in the captured image. An occlusion heat map may also be generated for the captured image. The occlusion heat map may include values representing the amount of occlusion in regions of the face. The estimated locations of the eyes, mouth, and nose may be used in combination with the occlusion heat map to assess occlusion scores for the landmarks. The occlusion scores for the landmarks may be used control one or more operations of the device.

  • Patent number: 10880742
    Abstract: In an embodiment, a method comprises determining, by a portable device, image capturing conditions by analyzing contents of a particular digital image of one or more first digital images captured by one or more image capturing devices. It is also determined whether the image capturing conditions indicate indoor image capturing conditions. If the image capturing conditions indicate indoor image capturing conditions, then it is determined whether the particular digital image includes a depiction of at least one eye. If so, an iris region, depicting the at least one eye, is segmented in the particular digital image. If the segmented iris region does not include iris valid information, then one or more image capturing devices capture one or more second digital images having an enhanced contrast. If the one or more second digital images include iris valid information, then iris code is extracted from the one or more second digital images.
