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 herein a method of removing a point cloud outlier and an apparatus implementing the method. The method includes: arranging a point cloud obtained from a laser scanner along at least a first direction; selecting, neighboring first-axis points, between which a separation degree satisfies an inspection start threshold condition, as a first leading-side representative point and a first trailing-side representative point; selecting a first leading-side outlier candidate and a first trailing-side outlier candidate based on a first leading-side separation degree and a first trailing-side separation degree; and determining the first leading-side outlier candidate and the first trailing-side outlier candidate as a first outlier point, when the number of the outlier candidates satisfies an allowable threshold condition.

Abstract: Provided are a texture mapping method using a reference image, and a computing apparatus. In detail, a texture mapping method may provide color continuity using a reference image and a target image with respect to each triangular face without analyzing a spatial configuration of a three-dimensional mesh model, thereby reducing a sense of color difference with respect to a texture, and improving quality of the three-dimensional mesh model.
