A method of encoding an immersive video according to the present disclosure includes determining whether an input image is a first type, converting the input image into the first type when the input image is a second type different from the first type, encoding a converted image, and generating metadata for the encoded image.

Method for decoding immersive video and method for encoding immersive video

Disclosed herein is a method for piecewise linear scaling of a geometry atlas, the method including generating min-max normalized depth values and generating geometry atlases by scaling the depth values so as to correspond to the gradients of multiple linear intervals.

Method of piecewise linear scaling of geometry atlas and apparatus using the same

A method of generating a hologram includes receiving an input image representing a 3D object, defining a first phase value for a first pixel data such that spatio-temporally identical pixels with respect to the input image have the same phase, defining a second phase value for a second pixel data such that spatio-temporally identical pixels with respect to the input image have the same phase, and generating a multi-view hologram using the first phase value and the second phase value.

Method for generating hologram

Provided is a method for converting a hologram resolution of an apparatus for converting a hologram resolution. The apparatus for converting a hologram resolution includes receiving a hologram data and determining a direction and a height of an envelope for the hologram data based on first information associated with the hologram data. The apparatus for converting a hologram resolution includes converting the resolution of the hologram data from a first resolution into a second resolution based on the envelop having the determined direction and height.
