Matlab-FFT

用递归法将一个整数n转换成字符串（例如输入4679，应输出字符串“4679”），n为不确定数，可以是位数不超过5，且数值在-32768~32767之间的任意整数。 (Recursive method to convert a string to an integer n (for example, type 4679, should output the string " 4679" ), n is the number of uncertainty, which can be not more than 5 digits, and the values in an arbitrary-32768 ~ 32767 integer.)

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 .)
