SVD_DWTimage
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 .)

exercise319a
(MATLAB) On the companion website, you will find in the directory Chap exercises/chapter3 a
workspace ex3M2.mat. In this workspace, you will find waveforms of the words “we” and “be” (at
10000 samples/s) in the array we be 10k. The waveforms and a spectrogram of the waveforms are
shownin Figure 3.33. To display the spectrogram andwaveform, use the function specgram ex3p19.m
also in Chap exercises/chapter3. To listen to the waveform, use the MATLAB function sound.m.
