Abstract: The present invention relates to a method and apparatus for encoding a displacement video using image tiling. A method for encoding multi-dimensional data according to an embodiment of the present disclosure may comprise: converting the multi-dimensional data into one or more frames with two-dimensional characteristics; generating one or more frame groups by grouping the one or more frames with pre-configured number units; reconstructing frames belonging to each frame group into a tiled frame; and generating a bitstream by encoding the tiled frame. Here, the tiled frame may be constructed with one or more blocks, and each block may be constructed by rearranging pixels existing at the same location in the frames.

Abstract: A method of encoding a dynamic mesh includes creating a base mesh through mesh decimation, subdividing the base mesh, extracting displacement information for the subdivided mesh, and encoding the base mesh and the displacement information. In this instance, mesh subdivision information for subdivision of the base mesh is encoded and signaled.
