    摘要: The processing of a stereoscopic image using first and second images to facilitate computing a corresponding depth/disparity image can be facilitated by providing (101) the first and second images and then computing (103) a disparity value of each pixel in the second image by, at least in part, determining a likelihood of occlusion for at least some pixels comprising the second image using, at least in part, predicted occlusion information as corresponds to information contained in the first image. By one approach, this predicted occlusion information can be provided, at least in part, by processing (102) the first image, at least in part, by determining occlusion value information for at least some pixels as comprise the first image and then using the occlusion value information for the first image to determine a corresponding disparity information map for the first image.

    摘要: A block encoder is operable to encode a target region of an image. The encoder encodes blocks from a target region of an image. The encoded blocks are stored in a scan order of the image. The encoded blocks are reordered into a scan order for the target region, and are output as an encoded image bit stream.

    摘要: A projection system that prevents projection light on a presenter and provides a gesture based interface for visual enhancements is disclosed. The system may include a projector camera system comprising a computer communicating an image to a projector, the projector projecting the image on a screen, a stereo camera unit mounted approximately in the plane of the screen or at the projector and directed toward the presenter and communicating with the computer, and software that interprets the stereo camera data to distinguish and manipulate foreground and background features. The foreground feature may be the presenter relative to the screen or to the audience and room, or the presenter's hand relative to the presenter. The invention employs imaging stereo camera algorithms and techniques developed for foreground/background segmentation, image manipulation, and gesture recognition.
