  • Publication number: 20220334638
    Abstract: Systems, apparatus, articles of manufacture, and methods for eye gaze correction in camera image streams are disclosed. An example apparatus disclosed herein includes timing circuitry to calculate a duration of time for which an eye gaze of a first user of a video conference is directed toward a second user of the video conference, the second user presented as an image via a video conference interface, the video conference interface presented by a display of an electronic device, and social feedback control circuitry to select an eye gaze time threshold based on content associated with the video conference interface, and in response to the duration satisfying the eye gaze time threshold, cause an alert to be presented on the display with the video conference interface.

  • Publication number: 20140334545
    Abstract: Methods and apparatus for video processing are disclosed. In one embodiment the work of processing of different types of video frames is allocated between a plurality of computing resources. For example, different computing resources for can be used for I, P and B frames, where an I frame is an intra-frame encoded with no other frames as a reference; a P frame is encoded with one previous I or P frame as a reference and a B frame is encoded with one previous and one future frame as references. In one example, a central processing unit (CPU) performs encoding of I frames and P frames of a video and a graphics processing unit (GPU) performs initial encoding of B frames of the video in connection with a fixed function video encoder configured to perform entropy encoding of the B frames.
