METHOD, AN APPARATUS AND A COMPUTER PROGRAM PRODUCT FOR CODING A 360-DEGREE PANORAMIC VIDEO |
| 摘要 |
There are disclosed various methods, apparatuses and computer program products for video encoding. In some embodiments the method comprises reconstructing a 360-degree panoramic source picture for inter-layer prediction; deriving an inter-layer reference picture from the 360-degree panoramic source picture, wherein the deriving comprises one or both of: upsampling at least a part of the 360-degree panoramic source picture, wherein said upsampling comprises filtering samples of a border region of the 360-degree panoramic source picture using at least partly one or more sample values of an opposite side border region and/or one or more variable values associated with one or more blocks of the opposite side border region; determining a reference region that crosses a picture boundary of the 360-degree panoramic source picture, and including in the reference region one or both of the following: one or more sample values of an opposite side border region; one or more variable values associated with one or more blocks of the opposite side border region. |

1. A method comprising
reconstructing a 360-degree panoramic source picture for inter-layer prediction; deriving an inter-layer reference picture from the 360-degree panoramic source picture, wherein the deriving comprises one or both of:
upsampling at least a part of the 360-degree panoramic source picture, wherein said upsampling comprises filtering samples of a border region of the 360-degree panoramic source picture using at least partly one or more sample values of an opposite side border region and/or one or more variable values associated with one or more blocks of the opposite side border region;determining a reference region that crosses a picture boundary of the 360-degree panoramic source picture, and including in the reference region one or both of the following:
one or more sample values of an opposite side border region;one or more variable values associated with one or more blocks of the opposite side border region. |
