摘要:
数字图像、音频和视频等多媒体数字产品愈来愈需要一种有效的版权保护方法。数字水印技术则为上述问题提供了一个有效的解决方案。数字水印技术将数字、序列号、文字、图像标志等版权信息嵌入到多媒体数据中,以起到版权保护、秘密通信和产品标识等作用。文中针对JPEG2000的渐进压缩编码特性,利用四叉树编码算法和变换域数字水印算法在JPEG2000中实现了一种渐进水印方案。此方案在VC6.0中实现,根据实验结果,证明该方法是有效的并且对原有的JPEG2000编解码过程基本没有增添复杂度
Abstract:
Multimedia digital products, such as digital image, audio and video need a more efficient method for copyright protection. The watermark technology provides an efficient solution to these kinds of issues. The digital watermark technology embeds digitals,serial numbers, words and image logs into multimedia database in order to protect copyright information, secrete communieation and product identifier, etc. A method to realize progressive digital watermark in JPEG2000 is introduced and the method is suitable for the character of progressive coding in JPEG2000. The method adapts the algorithm of coding of quadtree ,and the algorithm of transformation field. It is realized in VC6.0 and is proved to be effective by the experiment results
