说明：  提出了一种新的基于离散小波变换(DWT)与奇异值分解(SVD)相结合的数字图像水印算法。该算法将原始图像作小波分解并将小波分解得到的低频子带进行分块，对每一块进行奇异值分解后，选取每块中最大的奇异值通过量化的方法嵌入经过Arnold置乱后水印信息。(A new wavelet transform based on discrete (DWT) and Singular Value Decomposition (SVD) combination of digital image watermarking algorithm. The algorithm for wavelet decomposition of the original image and wavelet decomposition low-frequency sub-band are divided into blocks, each a singular value decomposition, the selection of each block by the largest singular value methods to quantify Arnold scrambled after embedding the watermark .)

AN INTRODUCTION TO MATRIX MANIPULATION IN MATLAB The power that MATLAB brings to digital image processing is the extensive set of functions that are available in MATLAB for processing multidimensional arrays, of which matrices (two dimensional numerical arrays) have a one to one correspondence with digital images. This tutorial discusses and illustrates a number of ways used to manipulate matrices. Usually, this is the first step in learning how to apply MATLAB tools to image processing applications.

说明：  物元分析法由我国数学家蔡文在 20 世纪 80 年代提出． 应用物元法建立多指标评价模型，可以针对复杂问题建立形象化模型，定量化得出评价结果，从而较完整、准确地反映事物的综合水平。利用matlab编程，进行如下步骤计算：1、待判物元的确定；2、经典域、节域的确定；3、关联函数；4、综合关联度(Matter-element analysis method was put forward by Chinese mathematician Cai Wen in 1980's. Applying matter-element method to establish multi-index evaluation model can establish visualization model for complex problems and quantify the evaluation results, so as to reflect the comprehensive level of things more completely and accurately. Using MATLAB programming, the following steps are calculated: 1. determination of the subject element to be judged; 2. determination of classical domain and node domain; 3. correlation function; 4. comprehensive correlation degree)
