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.
