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.

Description

technical field [0001] The present application relates generally to generating video data, and more particularly to the encoding of 360-degree video using region-adaptive smoothing. Background technique [0002] 360-degree video is a new way to experience immersive video using devices like GearVR. By capturing a 360-degree view of the world, 360-degree video enables consumers to experience immersive "real life," "being there" experiences. Users can change their point of view and dynamically view any part of the captured scene they desire. 360-degree video requires a higher bit rate than conventional video due to the increased video resolution (4K and higher) required to support a wider field of view. Increased bit rates are the limiting factor in delivering high-quality 360-degree immersive video viewing experiences to consumers. [0003] Therefore, the bit rate requirement is also higher, forcing the need for efficient compression. 360-degree video has unique properties...
