[Software Engineering] soft-barron-s60 DL : 0: Coefficients a and b control the low and high frequency ranges that the watermark affects. Because of the watermark invariant properties, we embed the watermark only in the Fourier descriptor magnitude. We use the inverse Fourier transform of the Fourier coefficients to produce the watermarked curve L . This watermarking method is also applicable in the control points of B-spline contour representations. In both polygonal curves and in B-spline curves, watermark embedding can create curve discontinuities or curve self-crossing.

[Special Effects] color-image-watermark DL : 0: 【转】针对彩色载体图像，提出了一种彩色图像超复数频域的水印算法。它通过对彩色载体图像进行快速超复数傅氏变换，在超复数频域选择合适频段嵌入水印，并且修改其对称系数的值，保证了嵌入水印图像仍然可以用彩色图像的红、绿、蓝三色进行传输。分析表明提出的方法通过超复数傅氏逆变换，可以把水印带来的误差扩散到整幅图像，并且是分散到红、绿、蓝三色的各个分量上，从而实现数字水印的不易感知性和安全性的良好结合。本算法还提出了对水印数据进行“交叉冗余嵌入”的规则，以进一步提高数字水印的鲁棒性。最后给出了实验结果，验证了本算法的优越性-[Turn] for color vector image, proposed a color image watermarking algorithm hypercomplex frequency domain. It is through the color vector images hypercomplex fast Fourier transform in the frequency domain over the complex to choose the right band watermarked, and modify the value of its symmetric coefficients, to ensure that the watermarked image can still use color images of red, green and blue color transmission. Analysis shows that the method proposed by hypercomplex Fourier inverse transform, the error can be caused by diffusion of the watermark to the entire image, and is dispersed to the respective components of red, green, and blue, so that digital watermark is not easy perceptibility and a good combination of safety. The algorithm is also proposed for the watermark data " Cross redundant embedded" rule, in order to further improve the robustness of digital watermarking. Finally, the experimental results verify the superiority of the algorithm
