1) transposition trees
对换树
2) Dual-tree wavelet transform
对偶树小波变换
4) dual tree complex wavelet transform
对偶树复小波变换
1.
The basic idea presented in this paper is the use of two appropriate dictionaries,one for the representation of texture parts-the dual tree complex wavelet transform and the other for the cartoon parts-the second generation of curvelet transform followed by a projected regularization method which is employed to better direct the separation process and reduce .
该方法的基本思想是用两个适当的字典:一个用来描述纹理部分——对偶树复小波变换,另一个用来描述结构部分——基于投影正则化方法的二代曲线波变换,其中投影正则化方法可以很好地指引分解过程,减少伪吉布斯现象。
2.
An image denoising method is proposed based on dual tree complex wavelet transform and Bayesian estimation.
基于对偶树复小波变换和贝叶斯估计技术,提出了一种图像噪声去除方法。
3.
In order to overcome the shortcoming of the commonly-used denoisng methods, the image denoising method based on dual tree complex wavelet transform (DT-CWT) is proposed.
为了克服上述离散小波变换图像去噪的不足,提出了利用对偶树复小波变换与双变量收缩函数相结合的图像去噪算法。

: Generally,we often use the notions of transposition and cyclic transformation etc for definit-ing deferminant.
定义行列式时,一般要用到对换、置换等概念,置换群还是有限群的一个重要例子,本文对这些概念反轮换作一些探讨,得到了一些结果。
