[Software Engineering] Image_Paper_YiKaiXiang DL : 0: 自适应二维数字水印系统随着因特网和数字技术的发展，数字媒体已成为人们获取知识的主要手段，但这也带来了一系列问题：如作品侵权、非法复制和传播等。而数字水印技术作为版权保护的重要手段，已得到广泛的研究和应用。本文提出了一种以灰度图象为水印的空域二维自适应数字水印算法。为实现水印图象的叠加，我们首先将其进行8 8分块并进行DCT变换，然后对每块的DCT系数进行量化和调整，最后，取出每块的部分DCT系数构成水印信号。为了实现自适应，首先将载体图象按8 8分块并利用视觉掩蔽特性对载体图象象素进行分类，根据块分类结果，水印信号以不同强度嵌入到载体图象中。实验结果表明，我们提出的算法具有较好的鲁棒性。最后本文对该技术今后的研究指出了一些可能的方向。
