  • Publication number: 20190266429
    Abstract: A classifier for detecting objects in images can be configured to receive features of an image from a feature extractor. The classifier can determine a feature window based on the received features, and allows access by each decision tree of the classifier to only a predetermined area of the feature window. Each decision tree of the classifier can compare a corresponding predetermined area of the feature window with one or more thresholds. The classifier can determine an object in the image based on the comparisons. In some examples, the classifier can determine objects in a feature window based on received features, where the received features are based on color information for an image.

  • Patent number: 8938519
    Abstract: Devices, systems, methods, and other embodiments associated with configuring devices are described. In one embodiment, a method includes receiving, from a remote device, a search input for an adjustment parameter. The method searches for the adjustment parameter in a television device based, at least in part, on the search input, wherein the adjustment parameter is a setting in the television device that controls how content is displayed. After the adjustment parameter is found, the adjustment parameter is returned to the remote device, which is caused to display the adjustment parameter. An input parameter value for changing the adjustment parameter is received from the remote device. The television device is reconfigured by locally changing the adjustment parameter based at least in part on the input parameter value, wherein a content is displayed on the television device based on at least the changed adjustment parameter.

  • Patent number: 8860657
    Abstract: To improve contrast ratio of the image on a backlit display plane such as a liquid crystal display (“LCD”), each area of the image that has separately controllable backlight may be given full backlight until an average or composite brightness of the image in that area is less than a threshold value at which light leakage through the image from full-strength backlight begins to be noticeable by a viewer. For image areas with composite brightness less than that threshold, backlight brightness may be reduced in proportion to how much below the threshold the area's composite image brightness is. Backlight brightness may also be adjusted for other image aspects such as (1) the presence of bright pixels in an otherwise relatively dark area, (2) whether the area is adjacent to one or more other areas in which the image information is in motion, and/or (3) time-averaging of image information over several successive frames of such information.
