Description: 基于DCT域的图像数字水印技术：
摘要：数字水印技术作为数字媒体版权保护的有效办法，近年来在国内外引起了人们极大的兴趣。作者采用了DCT离散余弦变换的算法，对图像这种多媒体数字作品进行了数字水印的嵌入和检测研究。并且使用了高效实用的编程工具MATLAB来介绍了一种DCT域的图像数字水印嵌入和提取的实例，并且在最后对嵌入水印的图像进行了攻击实验，验证了该算法的鲁棒性和不可见性。-Based on the DCT domain image watermarking techniques: Abstract: Digital watermarking of digital media technology as an effective means of copyright protection, in recent years both at home and abroad has aroused great interest. The author adopted the DCT discrete cosine transform algorithms, the image of this multi-media digital works for the digital watermark embedding and detection research. And the use of efficient MATLAB programming tools useful to introduce a DCT domain image watermarking embedding and extraction examples, and in the final of the embedded watermark image of the attack experiments verify the robustness of the algorithm and non- Visibility.

Description: 这个是一个获取两个图像相似度的函数，对于图像处理和数字水印方面的编程者来说，会经常去计算两个图像的psnr值，从而来确定图像的相似度，使用matlab可以很方便的计算两个图像的psnr，但是由于matlab专业性很强，而且有没有版权保护，所以对于大批的使用VC语言的这方面的编程者，由于要经常使用而显得很麻烦。
通过调用get_psnr函数可以很方便的就得到两个图像的相似度。
-This is a similarity to obtain a function of two images for image processing and programming aspects of digital watermarking are concerned, will keep the two images to calculate the PSNR value, thereby to determine the similarity of images, the use of matlab can be easily the calculation of the two images psnr, but because matlab highly professional, and has no copyright protection, and therefore the use of a large number of VC language programming in this area, and due to frequent use, there appears to be very troublesome. Get_psnr by calling the function can be easily obtained from the two images on the similarity. Platform: |

Description: 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.
