查询词典 entropy

Present a new LVQ wavelet image coding algorithm in which entropy coding and enumeration codes of different length are utilized. For wavelet image coding, there is a problem of mismatch between lattice distribution and the input vector probability density function in traditional LVQ algorithms (such as product-code pyramid VQ and piecewise uniform LVQ).

提出一种使用熵编码和非等长枚举码的格点矢量量化算法用于小波图象的编码，该算法以格点标记码码长的变化来适应输入矢量的非均匀分布，解决了传统的乘积码塔形矢量量化和分块均匀格点矢量量化算法中格点的调整难以与输入矢量概率分布实现良好匹配的问题。

And we show the form of the reduced density matrix master equation and its solution at first .Then we derive the solutions of Ohmic spectrum and Laurent series spectra master equations.
