摘要： An apparatus and a method for encoding key data are provided, which can increase the efficiency of encoding key data by identifying a linear key data region in input differential data. The key data encoder includes a linear key encoder, a floating-point number converter, a quantizer, an entropy encoder, and a key header encoder. When key data are input into the key data encoder, the linear key encoder searches for a region where key data linearly increases, i.e., a linear key data region, in the input key data and outputs the beginning and ending key data of the linear key data region to the floating-point number converter. The input key data except for the linear key data region are input into the quantizer. The key data input into the quantizer are quantized with predetermined quantization bits and are output to the entropy encoder. The entropy encoder encodes the quantized key data input from the quantizer and outputs the result as a bitstream. The floating-point number converter converts the beginning and ending key data of the linear key data region which are represented by binary numbers into the decimal system and outputs the results of the conversion to the key header encoder so that they can be included in the bitstream. The key data encoder may further include a quantization error minimizer.

摘要： Provided are methods and apparatuses for encoding and decoding three-dimensional object data, which consists of point texture data, voxel data, or octree data. The method of encoding three-dimensional object data involves generating three-dimensional object data having a tree structure in which nodes are attached labels indicating their types; encoding nodes of the three-dimensional object data; and generating the three-dimensional object data whose nodes are encoded into a bitstream. The apparatus for encoding three-dimensional object data includes a tree structure generator which generates three-dimensional object data having a tree structure in which nodes are attached labels indicating their types; a merging order selector which merges the nodes of the three-dimensional object data by referring to their labels; a node encoder which encodes merged nodes; and a bitstream generator which generates the three-dimensional object data whose merged nodes are encoded into a bitstream. The method of decoding three-dimensional object data involves reading continue flag information from a bitstream of encoded three-dimensional object data and decoding the continue flag information; decoding note type information of the bitstream; decoding an 'S' node if the note type information indicates that a current node is an 'S' node and decoding a PPM node if the note type information indicates that the current node is a PPM node; and restoring the three-dimensional object data whose nodes are encoded to a tree structure. The apparatus for decoding three-dimensional object data includes a bitstream reader which receives a bitstream of encoded three-dimensional object data; a node decoder which decodes the bitstream; and a tree structure restorer which restores decoded nodes to a tree structure.
