Matlab source code for DCT-based watermarking for grayscale images. DCT-based watermark recovering without resorting to the uncorrupted original image. Digital watermarking has been proposed as a viable solution to the need of copyright protection and authentication of multimedia data in a networked environment, since it makes possible to identify the author, owner, distributor or authorized consumer of a document. A new watermarking technique to add a code to digital images is presented: the method operates in the frequency domain embedding a pseudo-random sequence of real numbers in a selected set of DCT coefficients. Watermark casting is performed by exploiting the masking characteristics of the Human Visual System, to ensure watermark invisibility. The embedded sequence is extracted without resorting to the original image, so that the proposed technique represents a major improvement to methods relying on the comparison between the watermarked and original images.

有两种方法可以向脚本节点中输入 MATLAB脚本。 ( 1)使用 Operating 或Labeling 工具直接向MATLAB 脚本节点中输入脚本 （2）可以直接导入写好了的脚本 ,方法是使用鼠标右健单击 MATLAB 脚本节点,从快捷菜单中选Import,从打开的 Choose a script 选择脚本对话框中选择要导入的文件并单击 Open, MATLAB 脚本文本将出现在脚本节点中。为了便于调试 ,建议在导入脚本到 LabVIEW 之前 ,先在 MATLAB 环境内编写并运行。 (Continuous and discrete systems. The system that all its variables are continuous functions of time is called continuous-variable or analog system the describing equations are differential equations. )
