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: Disclosed are a method for manufacturing method a puff and the puff manufactured thereby. The method for manufacturing a puff comprises steps of: a) making a perforated cloth by perforating and cutting a puff cloth using a laser perforation apparatus; b) making a puff base by molding the perforated cloth; c) manufacturing a solid powder which includes a porous material which was inserted into a powder and compressed together with same; d) inserting the solid powder into the puff base; and e) manufacturing a puff by covering by sewing the puff cover onto the puff base.
