Abstract: The paper proposes a watermark scheme based on resolution and matrix decomposition.Experimental results show that the watermark scheme is robust to filtering,compression and noise adding,and also withstands cropping and geometric distortion.

摘要： 提出了一种结合分辨率变化和矩阵分解的数字图像水印算法。实验结果证明，该算法对滤波、压缩、噪声等有较好的鲁棒性，对几何变形和裁剪也有一定的抵抗力。
