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.

本内容为，三维模型直接导入matlab中，可以方便的运行，可以更观的体现模型的真实性(This content is, three-dimensional model directly into matlab, you can easily run, you can view more manifestation of the authenticity of the model)

这学期开了软件工程工具及其应用这么课，任老师给我们教了matlab程序设计语言，做了课程实验，自己用matlab实现了计算器，发现MATLAB确实是一门很有用得计算机编程语言，它把数值计算和可视化环境集成到一起，非常直观，而且提供了大量的函数，功能强大，工应用范围广泛。 (Opened this semester and its application software engineering tools such class, any teacher taught us matlab programming language, has done a course experiments using matlab realize their own calculators, found that MATLAB is indeed a very useful computer programming language , which the numerical computation and visualization environment for integrated together, very intuitive, but also provides a large number of functions and powerful, the broad scope of application.)
