经典的利用SVD进行数字图像水印的嵌入与提取，代码完整，可以运行，自带测试图像。
数字水印（Digital Watermarking）技术是将一些标识信息(即数字水印)直接嵌入数字载体(包括多媒体、文档、软件等)当中，但不影响原载体的使用价值，也不容易被人的知觉系统(如视觉或听觉系统)觉察或注意到。通过这些隐藏在载体中的信息，可以达到确认内容创建者、购买者、传送隐秘信息或者判断载体是否被篡改等目的。数字水印是信息隐藏技术的一个重要研究方向。

Digital watermark technology (Digital Watermarking) is the identification information (digital watermark) is embedded directly into the digital carrier (including multimedia, documentation, software, etc.) does not affect them, but the value in use of the original carrier, is not easy to be the human perception system ( such as visual or auditory system) perceived or noticed. Can be achieved through these information hidden in the carrier confirm the content creator, purchase, transmit secret information, or to judge the carrier has been tampered with such purposes. The digital watermark is an important research direction of information hiding technology.
