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.

Method for encoding and decoding a multi-view video

A method for processing multi-view video data including, for at least one block of an image of a view encoded in an encoded data stream representing the multi-view video, obtaining at least one information item, which specifies a mode for obtaining a synthesis data item, from among first and second obtaining modes. The synthesis data item is used to synthesize at least one image of an intermediate view of the multi-view video, the intermediate view not being encoded in the encoded data stream. The first obtaining mode involves decoding an information item representing the synthesis data item from the encoded data stream, the second obtaining mode involves obtaining the synthesis data item from at least the reconstructed encoded image. At least one part of an image of the intermediate view is synthesised from at least the reconstructed encoded image and the synthesis data item obtained by the specified mode.

Method and device for processing multi-view video data with synthesis data

A method and a device for processing multi-view video data. The multi-view video data includes at least one part of a decoded image of at least one view of the multi-view video, from an encoded data stream representative of the multi-view video. At least one item of data, referred to as synthesis data, is obtained from at least the one part of the decoded image, and at least one image of an intermediate view of the multi-view video not encoded in the encoded data stream is synthesized from at least the one part of the decoded image and from the synthesis data obtained.
