EZW
Shapiro提出的内嵌零树小波编码算法(EZW Embedded Zerotree Wavelet),其出发点在于小波变换后各级子带系数之间在空间上和方向上所呈现出带间相似性,这种空间相似性可以用一种新型的数据结构--零树(Zerotree).EZW算法就是充分利用这种相似性,获得高性能的图像编码算法.(Shapiro' s embedded zero tree wavelet coding algorithm (EZW Embedded Zerotree Wavelet), whose starting point is at all levels of sub-band wavelet transform coefficients and the direction in space with the similarity between shows, this space can be similar with a new data structure- zero tree (Zerotree). EZW algorithm is to take full advantage of this similarity, access to high-performance image coding algorithms.)

Laplace
传统的短时谱估计语音增强算法通常假设语音谱分量相互独立，没有考虑语音谱分量间的相关性。针对这
一问题，该文提出一种新的基于多元Laplace分布模型的短时谱估计算法。首先，假设语音的离散余弦变换(DCT)
系数服从多元Laplace分布，以此利用谱分量间的相关性；在此基础上，利用多元随机矢量的高斯尺度混合模型表
示，推导得到语音DCT系数矢量的最小均方误差(MMSE)估计的解析表达式；并进一步推导了基于该分布模型的
语音存在概率，对最小均方误差估计子进行修正。实验结果表明，该算法在抑制背景噪声和减少语音失真等方面优
于传统的语音增强方法。(The spectral components of speech are usually assumed to be independent in traditional short-time
spectrum estimation, which is not the case in practice. Tosolve this problem, a new speech enhancement algorithm
with multivariate Laplace speech model is proposed in this paper. Firstly, the speech Discrete Cosine Transform
(DCT) coefficients are modeled by a multivariate Laplace distribution, so the correlations between speech spectral
components can be exploited. And then a Minimum-Mean-Square-Error (MMSE) estimator based on the proposed
model is derived using a Gaussian scale mixture representation of random vectors. Furthermore, the speech
presence uncertainty with the new model is derived to modify the MMSE estimator. Experimental results show
that the developed method has better noise suppression performance and lower speech distortion compared to the
traditional speech enhancement method. )
