| 摘 要： | 提出了一种基于Kalman滤波的数字水印算法,利用图像融合的思想和Kalman滤波对数字水印进行了研究.嵌入水印的过程可以视为宿主图像和水印图像的图像融合的过程.假设嵌水印图像作为目标状态,在图像融合过程中,采用Kal-man滤波对观测状态进行最优估计.根据宿主图像和水印图像进行建模,得到观测方程和状态方程,在估计误差... |

| Abstract: | A digital watermarking algorithm based on Kalman filter is proposed.The watermarking algorithm is researched according to the image fusion and Kalman filtering.The process of watermarking can be viewed as a process of image fusion from the original image and the watermark image.Assuming that the watermarked image is the steady-state,Kalman filter is used as an optimal estimation algorithm in the process of image fusion.The math model is built according to the watermark image and the original image.Then the ... |
