Abstract
A video system for encoding or decoding 360-degree virtual reality (360VR) video is provided. The system performs filtering operations to reduce coding artifacts and discontinuities in a projection image of an omnidirectional image. The video system identifies first and second edges of the projection image. The first and second edges are physically correlated as a common edge in the omnidirectional image but not physically connected in the projection image. The system computes a set of filtered pixels based on a first set of pixels near the first edge and a second set of pixels near the second edge.
Claims20
A method comprising:
- receiving a projection image of an omnidirectional image;
- identifying a first edge of the projection image;
- identifying a second edge of the projection image, wherein the first and second edges are physically correlated as a common edge in the omnidirectional image but not physically connected in the projection image;
- and
- computing a set of filtered pixels based on a first set of pixels near the first edge and a second set of pixels near the second edge.
An electronic apparatus comprising:
- a decoded picture storage capable of receiving and storing a projection image of an omnidirectional image;
- and
- a filtering circuit capable of:
- identifying a first edge of the projection image;
- identifying a second edge of the projection image, wherein the first and second edges are physically correlated as a common edge in the omnidirectional image but not physically connected in the projection image;
- and
- computing a set of filtered pixels based on a first set of pixels near the first edge and a second set of pixels near the second edge.
