抗几何失真和常见的盲检测图像处理操作成为图像水印中一项极具挑战性的任务。为了达到这一目的，本文提出了一种基于内容的水印方案，该方案将不变特征提取和利用Tchebihef矩嵌入水印相结合。首先采用Harris-Laplace检测器提取特征点，然后生成以特征点为中心的非重叠圆盘。这些圆盘不受缩放和平移扭曲的影响。对于每个盘，然后执行取向对准以实现旋转不变。最后，通过抖动调制将水印嵌入到每个磁盘的切比切夫矩的大小中，以实现对常见图像处理操作和盲检测的鲁棒性。使用标准基准Stirmark的仿真结果表明，该方法对各种几何失真和常见的图像处理操作具有较强的鲁棒性，并优于典型的图像水印方案。
Protection against geometric distortions and common image processing operations with blind detection becomes a much challenging task in image watermarking. To achieve this, in this paper we propose a content-based watermarking scheme that combines the invariant feature extraction with watermark embedding by using Tchebichef moments. Harris-Laplace detector is first adopted to extract feature points, and then non-overlapped disks centered at feature points are generated. These disks are invariant to scaling and translation distortions. For each disk, orientation alignment is then performed to achieve rotation invariant. Finally, the watermark is embedded in magnitudes of Tchebichef moments of each disk via dither modulation to realize the robustness to common image processing operations and the blind detection. Thorough simulation results obtained by using the standard benchmark, Stirmark, demonstrate that the proposed method is robust against various geometric distortions as well as common image processing operations and outperforms representative image watermarking schemes.
