  • opencv-fft2
    灰度图像的二维傅里叶变换(cv_gray_fft2),二维傅里叶变换结果的幅值计算(cv_abs),频谱平移(cv_gray_fft2shift),将数值归一化到0到255区间(cv_range_0to255)是非常常用的四个功能!所以写成四个函数,方便将来调用!附运行截图~并附对应的MATLAB程序!(Dimensional Fourier transform of the grayscale image (cv_gray fft2), two-dimensional Fourier transform results to calculate the amplitude (cv_abs), spectral translation (cv_gray_fft2shift), the value normalized to range 0 to 255 (cv_range_0to255) is very common four function! so written as four function to facilitate future calls! attached run shot- along with the corresponding MATLAB program!)

  • SVD-based-watermarking
    基于SVD的DCT域和DWT域的经典水印算法,该算法通过提取水印水印的主成分并把该主成分嵌入到奇异值矩阵,鲁邦性非常高。(the principal components of the watermark are embedded into the host image in discrete cosine transform (DCT) and for the second method, those are embedded into the host image in discrete wavelets transform (DWT). To improve the robustness, the particle swarm optimization (PSO) is used for finding the suitable scaling factors. )
