    Abstract: Methods and apparatus of compression for pre-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. At the encoder side, stitching information associated with a stitching process to form the pre-stitched pictures is used to encode a current block according to embodiments of the present invention, where the stitching information comprises calibration data, matching results, seam position, blending level, sensor data, or a combination thereof. In one embodiment, the stitching information corresponds to matching results associated with a projection process, and projection-based Inter prediction is used to encode the current block by projecting a reference block in a reference pre-stitched picture to coordinates of the current block. In another embodiment, the stitching information corresponds to seam information associated with seam detection, and seam-based Inter prediction is used to encode the current block by utilizing the seam information.

    Abstract: A controller for generating an output image to be rendered on a transparent display panel is provided. The controller is configured to: receive an input image; calculate an opacity of each pixel in the input image according to a predetermined equation associated with the transparent display panel; determine a display mode of one or more portions of the input image according to transparency indication information associated with the one or more portions of the input image, wherein the display mode corresponds to transparency of the one or more portions in the input image; and obtain the output image to be displayed on the transparent display panel according to the determined display mode of the one or more portion of the input image.

    Abstract: Methods and apparatuses pertaining to a simulated transparent device may involve capturing a first image of a surrounding of the display with a first camera, as well as capturing a second image of the user with a second camera. The methods and apparatuses may further involve constructing a see-through window of the first image, wherein, when presented on the display, the see-through window substantially matches the surrounding and creates a visual effect with which at least a portion of the display is substantially transparent to the user. The methods and apparatuses may further involve presenting the see-through window on the display. The constructing of the see-through window may involve computing a set of cropping parameters, a set of deforming parameters, or a combination of both, based on a spatial relationship among the surrounding, the display, and the user.

    Abstract: A wearable device interactive system and techniques, methods and apparatuses thereof are described. A wearable device may sense a user input by a hand of the user, analyze the user input, and perform one or more operations responsive to a result of the analysis. For example, the wearable device may launch an application corresponding to the user input. As another example, the wearable device may recognize a text at a fingertip of the user and determine a location of the wearable device to determine a context, and launch an application corresponding to the context.
