Abstract: Feature information is received from a client device and describes extended reality scene(s) in an extended reality (ER) environment at the client device. An ER description is formed in an ER description format corresponding to the feature information and is stored. Some of the stored ER description format is provided in a representational format upon request of the client device or other client devices viewing the one or more ER scenes and assisting the positioning of corresponding client devices in the ER environment. A client device captures environmental visual data and generates feature information, describing ER scene(s) in an extended reality environment at the client device, from the environmental visual data, and sends the generated feature information toward a server. A client device can localize itself in a 3D environment of an ER description, and generate ER anchors and objects, link them, and send them to a server.

Abstract: The embodiments relate to a method, and a technical equipment for implementing the method. The method comprises generating a bitstream defining a presentation, the presentation comprising an omnidirectional visual media content; and indicating in the bitstream a definition for an external media to be overlaid on the omnidirectional visual media content during rendering; wherein the definition comprises at least an overlay placement information for the external media on the omnidirectional visual media content. The embodiments also relate to a method and technical equipment for decoding the bitstream.

Abstract: The invention relates to a method comprising receiving, by a neural network, a first image comprising at least one target object; receiving, by the neural network, a second image comprising at least one query object; and determining, by the neural network, whether the query object corresponds to the target object, wherein the neural network comprises a discriminator neural network of a generative adversarial network (GAN). The invention further relates to an apparatus and a computer program product that perform the method.
