Methods, device and data stream are provided to encode unaligned multi-view plus depth images associated with assistance metadata for generating depth maps aligned with the unaligned color views. At the encoding stage, for an unaligned color view, the contribution of each depth map is evaluated. A subset of the most contributing depth maps is selected and metadata representative of this subset is encoded in the data stream of the unaligned multi-view plus depth images in association with the unaligned color view. At the decoding stage, to generate a depth map unaligned with the unaligned color view, only the depth maps referenced in the assistance metadata are warped.

Depth-color alignment with assistance metadata for transcoding of volumetric video

Methods and devices for encoding and decoding 3D scenes of an immersive video are disclosed with the related data stream. Taking advantage of the fact that parts of the 3D scene does not change from one frame of the video to another, even when the cameras move and/or the lighting condition change, dynamic and static parts of the 3D scene are encoded in different atlases. In an embodiment, static patch atlases are repeated between two updates. In another embodiment, only updates are encoded and transmitted. The decoder maintains a memory associating entity of the 3D scene with a set of static patches that is updated with instructions linked to update static patch atlases. At each presentation time the static part of the 3D scene to decode is obtained from the memory.

The invention proposes a method and device for protection of data for devices connected in a network such as a local area network or LAN. The method and device can for example be implemented on a gateway, which acts as an interconnecting device between the devices in the LAN network and that can offer these devices an access to an external network such as a wide area network or WAN. The method and device thus offers a protected environment for applications that are executed on the gateway, such as applications downloaded from the WAN. The method and device gives the applications executed on the gateway controlled access to the LAN resources in order to protect the data that the LAN devices share within the LAN, while giving the applications access to the WAN.

The present invention relates to the field of management of image data in data storage. In particular, the present invention relates to a method and device for automatic detection of duplicate images in data storage and corresponding device while taking into account user perception of what he considers to be duplicate images, which method and device are particularly efficient with regard to the personalized, automatic management of large amounts of image data.
