| 摘 要： | 提出了一种鲁棒性数字水印算法。该算法中水印嵌入的位置和强度均与原始图像有关。利用图像小波变换系数值和图像视觉的关系，通过有选择的修改小波变换系数实现水印嵌入，嵌入的水印具有良好的不可见性和鲁棒性，水印检测采用了盲检测和三取二判决技术。实验结果表明算法对常规图像处理尤其是乘性噪声具有很好的鲁棒性。

| Abstract: | By studying between the wavelet transform coefficient and image vision, a robust blind image digital watermarking algorithm is proposed. The algorithm related the position and intensity of embedded watermarks to original image. Watermarking detection used blind detection and two out of three adjudgement technique. The experilnental results show that the embedded watermarks with this algorithm prolosed are invisible and robust enough against the commonly used image processing techniques especially it had good mbusmess to multiplicative noise . |
