Description: 频域法加入数字水印的原理是首先将原始信号（语音一维信号、图像二维信号）变换到频域，常用的变换一般有DWT、DCT、DFT、WP和分形。然后，对加入了水印信息的信号进行频域反变换（IDWT、IDCT、DFT、WP），得到含有水印信息的信号。-Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of one-dimensional, two-dimensional image signal) to frequency domain transformation, commonly used in general transform DWT, DCT, DFT, WP and fractal. Then, adding the watermark information signal to the frequency domain inverse transform (IDWT, IDCT, DFT, WP), received signal containing the watermark information. Platform: |

Description: All three, Discrete Wavelet Transform (DWT) - Singular
Value Decomposition (SVD) and Adaptive Tabu Search
(ATS) have been used as mathematical tools for embedding
data into an audio signal. In this paper, we present a new
robust audio watermarking scheme based on DWT-SVD and
ATS. After applying the DWT to the cover audio signal, we
map the DWT coefficients, and apply the SVD, we search for
the optimal intensity of audio watermarking by using the
ATS. Experimental results show that the watermarking
method performs well in both security and robustness to
many digital signals processing, such as filtering,
cropping, mp3 and random noise. Platform: |
