摘    要:数字水印技术作为数字媒体版权保护的重要手段之一,近年来已成为国内外研究的热点.与传统的嵌入一个无意义的一维或二维伪随机序列以及可视的二值图像相比,嵌入灰度图像水印不仅嵌入信息量大,而且更加有意义.对灰度级数字图像水印技术的最新发展情况进行了介绍,主要内容包括:空域及变换域的灰度数字图像水印技术,其中变换域水印主要讨论了DCF域和DWT域两类灰度数字水印;自适应灰度级数字水印技术;灰度数字图像水印的性能评价.最后展望了该技术的进一步研究前景及可能的研究热点.

关 键 词:灰度级图像水印  变换  自适应

Abstract:As one of the key means for the protection of digital media copyright, digital watermarking has become a research highlight at home and abroad.Compared to the conventional embedding with a meaningless one-dimensional or two-dimensional pseudo-random sequence as well as a visible binary image,embedding with a grey-level image watermark is not only informative but meaningful.The latest development in grey-level image watermarking(GLIW) is introduced,The following three topics of the technique are discussed ma...
