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: 基于DWT的水印算法
对图像进行二层小波分解，提取出二层低频系数，随机选取一些像素，根据选定像素与其邻居的关系，确定水印的值
水印是根据图像来获得的，而不是提前得到的
根据论文 An Improved Robust Watermarking Technique in Wavelet Domain 编写-Based DWT watermark algorithm Layer wavelet decomposition, the image is extracted Layer low frequency coefficients, and randomly select some of the pixels, According to the relationship between the pixel and its neighbors is selected, it is determined the value of the watermark of the watermark is based on the image obtained, rather than in advance by According to the papers ' An Improved Robust Watermarking Technique in Wavelet the Domain' writing Platform: |
