Abstract: Systems and methods are described for providing spatial content using a hybrid format. In some embodiments, a client device receives, from a server, surface light field representations of a plurality of scene elements in a 3D scene, including a first scene element. The client device provides to the server an indication of a dynamic behavior of a second scene element different from the first scene element. Further, in response to the indication, the client device receives from the server information defining the first scene element in a 3D asset format. The client device then renders at least the first scene element in the 3D asset format.

Abstract: A method and apparatus of encoding/decoding attributes of points of a pint cloud are provided. The encoding method subdivides a bounding box bounding the points to be encoded, encodes data representative of attributes of a point by referring to a subdivision to which said point belongs to; and encode data representative of a number of points comprised in each subdivision.

Abstract: Some embodiments of a method may include obtaining an image a real-world environment, determining an estimated illuminant spectral power distribution of an illuminant of the real-world environment, and detecting a region of the image representing human skin. The method may further include determining a representative skin color value of the region and based on the estimated illuminant spectral power distribution and the representative skin color value most closely matching the representative color value, selecting a candidate skin reflectance spectrum. The method may further include updating the estimated illuminant spectral power distribution base on the representative skin color value and the selected candidate skin reflectance spectrum.

Abstract: At least one embodiment relates to a method for adding at least one 3D sample to a point cloud frame and for assigning a color-coding mode to said at least one 3D sample, said color-coding mode indicating if color information associated with said at least one 3D sample is explicitly encoded in a bitstream or if said color information is implicit.

Abstract: A method for reducing the parameters defining an acquired light field ray which enables only the colour associated with the light field ray to be stored instead of 4 light field co-ordinates (x,y,i,j) and its associated colour.

Abstract: Methods, apparatus, systems, devices, and computer program products directed to augmenting reality with respect to real-world places, and/or real-world scenes that may include real-world places may be provided. Among the methods, apparatus, systems, devices, and computer program products is a method directed to augmenting reality via a device. The method may include capturing a real-world view that includes a real-world place, identifying the real-world place, determining an image associated with the real-world place familiar to a user of the device viewing the real-world view, and/or augmenting the real-world view that includes the real-world place with the image of the real-world place familiar to a user viewing the real-world view.

Abstract: The present disclosure relates to methods, apparatus or systems for encoding and decoding sequence of images by applying a global rotation motion compensation to an input image. According to different embodiments, the input image is a reference image in a compression loop or the image to be encoded. The images to encode are omnidirectional images. As a result, applying a global rotation motion compensation to them corresponds to generate new images as if they have been captured according to a different front direction. When this new front direction is the one of a reference image, the compensation of apparent motion is facilitated.

Abstract: The present disclosure relates to a method and device for obtaining a second image from a first image when the dynamic range of the luminance of the first image is greater than the dynamic range of the luminance of the second image. The disclosure describes deriving at least one component representative of the colors of the second image from the first image, and maximizing at least one derived component according to a maximum value depending on a linear-light luminance component of the first image.
