Description: 本文是关于小波分析在图像处理压缩方面的应用，是word格式的，文档中有详细的程序和文字分析说明，对学习的人很有帮助。
在小波方法的实际应用中，可以利用尺度方程系数构造得到小波和小波包变换算法即金字塔算法。利用张量积方法可以从一维多分辨分析直接得到二维的多分辨分析，从而方便地构造得到二维小波和小波包以及相应的分解和合成算法。在图象处理和二维数据分析研究中广泛使用的就是二维形式的小波和小波包算法。-This article is about the treatment of wavelet analysis in image compression applications, is the word format, document in detail the procedures and text analysis, and learn helpful. Wavelet method in practical applications, can use the scale factor equation has been constructed wavelet and wavelet packet transform algorithm that is, the pyramid algorithm. Use of tensor product can be from one-dimensional analysis directly from the two-dimensional multiresolution analysis, thus conveniently be constructed of two-dimensional wavelet and wavelet packet and the corresponding decomposition and synthesis algorithms. In two-dimensional image processing and data analysis study is the widely used two-dimensional form of wavelet and wavelet packet algorithm. Platform: |

Description: 首先,给出了对应于多重多分辨分析的双正交多小波包的定义,建立了具有任意矩阵伸缩的双正交多小波包的理论框架.在此基础上,给出了具有任意矩阵伸缩的高维不可分双正交多小波包的构造方法.由此构造的多小波包的分解系数可以从不同的滤波器中抽取,这使得小波包的应用更灵活.
-First of all, given that corresponds to multiple multi-resolution analysis of biorthogonal multiwavelets package definition, the establishment of an arbitrary matrix scalable biorthogonal multiwavelet packets theoretical framework. On this basis, given an arbitrary matrix stretching high-dimensional nonseparable biorthogonal multiwavelet packets constructed. This structure of multi-wavelet packet decomposition coefficients can be from a different filter in the extraction, which makes the application of wavelet packet more flexible. Platform: |
