| 摘 要： | 为了实现数字多媒体产品的版权保护，提出一种基于图像局部特征区域的鲁棒水印方案。图像局部特征区域是利用Harris算子检测到的特征点构造得到的固定尺寸的纹理区域，具有很好的视觉掩蔽特性，同时图像特征点经过几何攻击后仍然可以保持，保证了水印隐藏位置检测的正确性。算法在每个局部特征区域利用奇异值分解操作得到的分量矩阵的特点实现水印信息的隐藏。实验结果表明，本算法能够在保证水印不可见性地同时，很好地抵抗如JPEG压缩、旋转等攻击。 |

| Abstract: | A robust image watermarking algorithm based on the local feature region is presented to realize the robust image watermarking algorithm.The local feature regions are constructed by the feature points detected by the Harris operator and they are the texture regions used for hiding the watermark information.The feature points are steady after the geometric attacks,meanwhile,so the local feature regions that hide the watermarks could be detected accurately.The application of the characteristics of SVD makes the watermark capable of transparent hiding.Simulation results show that the method performs well on resisting the JPEG compression and rotating attacks. |
