    摘要: An alpha matte is generated from image forming elements of an image. For each of one or more of the image forming elements: a respective representative foreground value is determined from one or more of the image forming element values; the respective representative foreground value and the value of the image forming element are normalized with respect to a threshold level; and a respective value of the alpha matte is generated from an evaluation of the normalized image forming element value in relation to the normalized representative foreground value.

    摘要: A video sequence control system that includes an input video frame buffer and an output video frame selection component is described. The input video frame buffer receives input video frames from a video source. The output video frame selection component determines the video frame to be output according to a scheduler that provides timing information and modulation information. The timing information includes information regarding when a video frame will be output. The modulation information varies dependent upon the frame types available to be output, wherein the available frame types include at least image frames from the input video frame buffer and functional frames, wherein the at least image frames and functional frames are output according to a pattern defined by the scheduler. In addition based on the timing information, a synchronization output signal is output corresponding to the output of the functional frame.

    摘要: Embodiments of the present invention disclose a system and method for focus-based touch detection. According to one embodiment, a reference pattern is formed on a surface and an imaging device is configured to detect the reference pattern and the presence of an object within proximity of a contact area of the surface. Furthermore, focus information associated with the reference pattern and/or object is used to determine if the detected object is touching or hovering said contact area.
