摘要
提出一种改进的拼凑算法,用来在空间域实现水印的嵌入和盲检测,算法在不影响原始图像视觉效果的基础上,对常见的图像攻击具有较好的鲁棒性。水印检测不需要原始图像的参与,有效实现了盲检测。
Presents an improved patch algorithm for watermarking embedding and extraction in spatial domain, the proposed watermarking scheme achieves better visual quality, and is robustness to general image attack, and the original image is not used for watermark extraction show that blind detection of watermark is achieved.
