Description: The classic use of SVD digital image watermark embedding and extraction, the code is complete, you can run, comes with a test image. 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.
