    • An apparatus for image coding using tree-structured vector quantization based on a wavelet transform and a method therefor are provided. The apparatus for image coding using a tree-structured vector quantization based on wavelet transform has a wavelet transform unit, a vector construct unit, an error vector unit, a scan unit, a first quantization unit and a second quantization unit. The wavelet transform unit wavelet transforms an input image signal. The vector construct unit constructs vectors, each having a tree structure in a different direction, using the wavelet transformed result. The error vector generation unit generates a plurality of error vectors by setting one of the vectors as a basic vector and performing a calculation on each of the vectors remaining with respect to the basic vector. The scan unit scans the coefficients of each of the basic vector and error vectors in a different direction. The first vector quantization unit generates a first codebook for the basic vector scanned in the scan unit, quantizes the scanned basic vector using the first codebook, and outputs the quantization result as the index of the first codebook. The second vector quantization unit generates a second codebook for the error vectors scanned in the scan unit, quantizes the scanned error vectors using the second codebook, and outputs the quantization results as the indices of the second codebook. According to the apparatus and method, the advantages of wavelet vector quantization and zerotree-coding are maximized so that the size of a codebook is reduced and the coding performance is improved.
    • 提供一种使用基于小波变换的树结构矢量量化的图像编码装置及其方法。 使用基于小波变换的树结构矢量量化的图像编码装置具有小波变换单位,矢量构造单位,误差向量单位,扫描单位,第一量化单位和第二量化单位。 小波变换单元小波变换输入图像信号。 矢量构造单元使用小波变换结果来构建每个具有不同方向的树结构的向量。 误差向量生成单元通过将其中一个矢量设定为基本矢量并对相对于基本矢量剩余的各矢量进行运算,生成多个误差矢量。 扫描单元沿不同的方向扫描每个基本向量和误差向量的系数。 第一矢量量化单元生成用于在扫描单元中扫描的基本矢量的第一码本,使用第一码本量化扫描的基本矢量,并输出量化结果作为第一码本的索引。 第二矢量量化单元生成用于在扫描单元中扫描的误差矢量的第二码本,使用第二码本对扫描的误差向量进行量化,并输出量化结果作为第二码本的索引。 根据该装置和方法,将小波矢量量化和零树编码的优点最大化,从而减小码本的大小,提高编码性能。

    • A method, medium, and apparatus extracting avatar parameters using an avatar transformation algorithm from health state information measured from a user and generating an avatar using the extracted parameters. In the apparatus, a state analysis unit receives at least one among a bio-signal and questionary information of a user and outputs health state information, a parameter extraction unit extracts parameters defining an avatar image, and an avatar generation unit generates the avatar image using the parameters. By providing the method, medium, and apparatus, it is possible to provide a user with a convenience in recognizing his health state by generating an avatar image describing the user's future health state as well as the user's current health state. Further, it is possible to induce a user to manage his health constantly by maintaining a user's with the avatar image change.
