Abstract: The application relates to a method for processing a 3D image data stream, the method including at a processing entity including receiving a first 3D image data stream including a preliminary visual appearance of at least a human, wherein the preliminary visual appearance of the human is to be transmitted to an extended reality device for display, determining additional parts to be added to the visual appearance of the human for completing the preliminary visual appearance to a final visual appearance to be displayed at the extended reality device. A parameter is received from the extended reality device influencing the final visual appearance of the human at the extended reality device, the additional parts are amended to adapted additional parts based on the received parameter, and the final visual appearance of the human is generated including adding the adapted additional parts to the preliminary visual appearance of the human.

Abstract: The invention relates to a method for processing 3D image data streams including at a processing entity in an audio-visual conferencing scenario: receiving, from an extended reality device, a first 3D image data stream representing a field of view of a first participant wearing the extended reality device, receiving a position of the extended reality device, receiving a second 3D image data stream representing at least one human representing at least a second participant, identifying first objects represented in the first 3D image data stream, identifying second objects represented in the second 3D image data stream, determining similarities between the first objects and the second objects, determining at least one forbidden area in the field of view of the first 3D image data stream, where a placement of a visual appearance of the human is to be avoided.

Abstract: An augmented reality. AR, computing server (200) includes a network interface (202), a processor (204), and a memory (206) storing instructions executable by the processor to perform operations. The network interface is configured to receive through a network a three-dimensional (3D) video stream from a user device during a conference session. The operations identify a video object captured in the 3D video stream, and determine a pose of the video object captured in the 3D video stream. The operations obtain AR context information from an AR display device indicating how the video object is to be posed relative to a physical object viewable through a see-through display of the AR display device, and adjust pose of the video object captured in the 3D video stream based on the AR context information. The operations output the video object to the see-through display for display. Related methods and computer program products are disclosed.
