现有水印方法的主要缺点是它们对广泛的几何攻击的抵抗力有限。此外，我们发现最初旨在抵抗几何攻击的多个水印嵌入方法的弱点是它们无法承受水印估计攻击（weas），从而降低了对几何攻击的抵抗力。鉴于这些事实，本文提出了一个可靠的图像水印方案，该方案可以同时承受几何变形并同时承受。我们的方案主要由三个组成部分组成：1）稳健的网格产生和基于网格的水印以抵抗几何变形； 2）构建基于介质的基于哈希的内容依赖性水印以抵抗羊毛； 3）一种假阳性水印检测的机制，可用于确定水印的存在，以实现正确检测和错误检测之间的权衡。此外，使用标准基准（即Stirmark）和Ways获得的广泛实验结果，并与相关的水印方法进行比较证实了我们在改善鲁棒性方面的出色表现。据我们所知，以前的文献尚未报道这样的彻底评估
The major disadvantage of existing watermarking methods is their limited resistance to extensive geometric attacks. In addition, we have found that the weakness of multiple watermark embedding methods that were initially designed to resist geometric attacks is their inability to withstand the watermark-estimation attacks (WEAs), leading to reduce resistance to geometric attacks. In view of these facts, this paper proposes a robust image watermarking scheme that can withstand geometric distortions and WEAs simultaneously. Our scheme is mainly composed of three components: 1) robust mesh generation and mesh-based watermarking to resist geometric distortions; 2) construction of media hash-based content-dependent watermark to resist WEAs; and 3) a mechanism of false positive-oriented watermark detection, which can be used to determine the existence of a watermark so as to achieve a tradeoff between correct detection and false detection. Furthermore, extensive experimental results obtained using the standard benchmark (i.e., Stirmark) and WEAs, and comparisons with relevant watermarking methods confirm the excellent performance of our method in improving robustness. To our knowledge, such a thorough evaluation has not been reported in the literature before
