    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 apparatus of compression for non-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. According to one embodiment, the system uses a RIBC (Remapped Intra Block Copy) mode, where the block vector (BV) or BV predictor is remapped using calibration data to reduce the search range. The mapped BV or BVP is also more efficient for coding. A color scaling process can be used with the RIBC mode to compensate the color/brightness discrepancy between images from different cameras. A projection-based Inter prediction method is also disclosed. The projection-based Inter prediction method takes into account different perspectives between two images captured from different cameras. Transform matrix is applied to a block candidate to project the block candidate to a position of a target block. The projected block candidate is used as a predictor for the target block.

    Abstract: A display method for video conferencing and an associated video conferencing system are provided. The video conferencing system includes a display, an image capturing unit, and a network interface unit. The method includes the steps of: utilizing the image capturing unit to capture images of a local user in a video conference; performing foreground segmentation on the captured images to obtain a foreground object; flipping the foreground object horizontally; identifying a human face from the flipped foreground object and correcting a facing angle of the human face; determining interaction data from the local user on the display; encoding the interaction data and the flipped foreground object into an interaction stream and a video stream, respectively; packing the interaction stream and the video stream into an output stream; and transmitting the output stream to a remote user of the video conference through the network interface unit.

    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.
