  • Patent number: 9885568
    Abstract: A camera at a fixed vertical height positioned above a reference plane, with an axis of a camera lens at an acute angle with respect to a perpendicular of the reference plane. One or more processors receive camera images of a multiplicity of people of unknown height and vertical axis of the images are transformed into pixel counts. The known heights of people from a known statistical distribution of heights of people are received by one or more processors and transformed to a normalized measurement of pixel counts, based in part on a focal length of the camera lens, the angle of the camera, and an objective function summing differences between pixel counts of the known heights of people and the unknown heights of people. The fixed vertical height of the camera is determined by adjusting the estimated camera height to minimize the objective function.

  • Patent number: 9848113
    Abstract: A system and method for authenticating a user of a device. A multi-band biometric iris scan camera system is capable of obtaining an iris image using near-infrared (NIR) light and/or visible wavelength (VW) light. The camera system can initially image a user to detect the iris color of the user and, based on the iris color, determine whether to use the NIR iris scan or the VW iris scan. Additionally, NIR and VW systems can be operated as integrated camera systems. The iris scan camera system can take a series of images and compare against a database of anonymous iris images captured at different illumination conditions, for selecting a preferred illumination condition for capturing the iris and performing authentication.

  • Patent number: 9838573
    Abstract: Methods, systems, and devices for guiding a subject back within the recognizable visual range of a multimedia system are described. According to one of the described methods, when it is determined that the target has left the recognizable range of the multimedia system, sensor information is acquired from a portable electronic device (or controller) the user has been using to control the multimedia system, and the acquired sensor information is used to determine where the user is, relative to the recognizable range. In one example, the user is asked to make a gesture with the portable electronic device, and the sensor information concerning that gesture is used to determine the user's relative location. In another example, the sensor information recorded at the time the user left the recognizable range is used to determine the user's relative location.
