Abstract
A method for coding views simultaneously representing a 3D scene from different positions or different view angles, implemented by a coding device. The method includes, for a depth component of at least one view: partitioning the depth component into at least one block; obtaining depth information of the at least one block from texture data of a texture component of at least one of the views; obtaining at least one depth estimation parameter from the information; and coding the at least one depth estimation parameter, the depth information of the at least one block not being coded.
Claims15
A method for coding views simultaneously representing a 3D scene from different positions or different view angles, implemented by a coding device, comprising the following, for a depth component of at least one view:
- partitioning said depth component into at least one block,
- obtaining depth information of said at least one block from texture data of a texture component of at least one of said views,
- obtaining at least one depth estimation parameter from said information, and
- coding said at least one depth estimation parameter, the depth information of said at least one block not being coded.
A device for coding views simultaneously representing a 3D scene according to different positions or different view angles, said coding device comprising:
- a processor which is configured to implement the following, for a depth component of at least one view:
- partitioning said depth component into at least one block,
- obtaining depth information of said at least one block from texture data of a texture component of at least one of said views,
- obtaining at least one depth estimation parameter from said information, and
- coding said at least one depth estimation parameter, the depth information of said at least one block not being coded.
(canceled)
A non-transitory computer-readable information medium, comprising instructions of a computer program stored thereon which when executed by a processor of a coding device cause the coding device to implement a method for coding views simultaneously representing a 3D scene from different positions or different view angles, the method comprising the following, for a depth component of at least one view:
- partitioning said depth component into at least one block,
- obtaining depth information of said at least one block from texture data of a texture component of at least one of said views,
- obtaining at least one depth estimation parameter from said information, and
- coding said at least one depth estimation parameter, the depth information of said at least one block not being coded.
A method comprising:

- reading, in a data signal, at least one depth estimation parameter associated with said at least one block,
- decoding said at least one depth estimation parameter, and
- obtaining depth information of said at least one block from said at least one depth estimation parameter and from texture data of a reconstructed texture component of at least one of said views.
