  • Patent number: 9769484
    Abstract: Disclosed is a method of decoding residual coefficients of a transform unit from a bitstream of video data. The method receives the transform unit (1500) from the bitstream of video data in which the transform unit has upper (1503) and lower (1502) level square layers. The upper level layer represents a square arrangement of at most four significant coefficient group flags with each of the significant coefficient group flags representing a non-overlapping region of the lower level layer. The method determines determining the significant coefficient group flags of the square upper level layer for the received transform unit, and determines values of residual coefficients of the square lower layer according to the determined significant coefficient group flags to decode the transform unit of the bitstream of video data. Corresponding encoding methods are also disclosed.

  • Patent number: 9767612
    Abstract: A method of removing a marker projected in a scene from a view of the scene. A first image of the scene is captured using a camera (e.g., 127A). A second image of the scene is captured, using the camera (127A), following a marker (310) being projected onto an object in the scene to indicate a reference location in the scene for positioning a virtual object, the second image containing a representation of the projected marker. The second image is interleaved with the first image. A data stream is formed using at least the first and second image to generate a view of the scene, the data stream containing data representing the virtual object as part of the captured images of the scene. The virtual object is positioned relative to the projected marker captured in the second image. Pixels from the first image are used as pixel values at pixel locations where the projected marker was located in the second image to remove the projected marker from the generated view of the scene.
