一种能够在有价值的图像中嵌入版权信息的数字水印技术已经引起了人们的关注。因此,我们提出了一种新的基于涂抹-去涂抹变换的数字水印方法,并给出了相应的算法。涂抹-去涂抹变换是一种将水印信息传播到整个图像上的新变换。在我们的方法中,我们可以很容易地计算出该方法在多大程度上降低了水印图像的嵌入能量。
The technology of a digital watermarking that can embed copyright information in valuable images has come to be paid attention. Therefore, we propose a new digital watermarking method using the Smearing-Desmearing transformation and show the algorithm. The Smearing-Desmearing transformation is a new transformation that watermark information is spread on the whole of an image. In our method, we can easily calculate how much the method degrades the quality of the watermarked image from embedded watermark energy.
