    Abstract: A video processing unit and method for region adaptive smoothing. The image processing unit includes a memory and one or more processors. The one or processors are operably connected to the memory and configured to stitch together a plurality of video frames into a plurality of equirectangular mapped frames of a video. The one or processors are configured to define a top region and a bottom region for each of the equirectangular mapped frames of the video; perform a smoothing process on the top region and the bottom region for each of the equirectangular mapped frames of the video; and encode the smoothed equirectangular mapped frames of the video.

    Abstract: A method is provided that includes receiving a bitstream. The method also includes parsing the bitstream for a flag indicating whether a palette was used from a first or second coding unit. The method also includes decoding the first coding unit using the palette from the first or second coding unit indicated by the flag. The palette is determined based on which palette of the first or second coding unit improves compression performance. Also, a method is provided that includes receiving a bitstream with a predicted pixel. A coding unit and a reference unit are identified. A number of pixels of the coding unit and the reference unit overlap. A set of available pixels and a set of unavailable pixels of the reference unit are identified. The predicted pixel of the set of unavailable pixels is estimated as a pixel of the set of available pixels.
