Title:
METHOD AND APPARATUS FOR GENERATING AND ENCODING PROJECTION-BASED FRAME THAT INCLUDES AT LEAST ONE PADDING REGION AND AT LEAST ONE PROJECTION FACE PACKED IN 360-DEGREE VIRTUAL REALITY PROJECTION LAYOUT
Document Type and Number:
WIPO Patent Application WO/2018/166430
Kind Code:
A1
Abstract:
A video processing method includes: receiving an omnidirectional content corresponding to a sphere, obtaining projection faces from the omnidirectional content, and creating a projection-based frame by generating at least one padding region and packing the projection faces and said at least one padding region in a 360 VR projection layout. The projection faces packed in the 360 VR projection layout include a first projection face and a second projection face, where there is an image content discontinuity edge between the first projection face and the second projection face if the first projection face connects with the second projection face. The at least one padding region packed in the 360 VR projection layout includes a first padding region, where the first padding region connects with the first projection face and the second projection face for isolating the first projection face from the second projection face in the 360 VR projection layout.
