| 摘 要： | 扩频和量化技术是数字水印中两种基本的技术,扩频水印有鲁棒性强的特点,而量化水印具有更大的容量,考虑到两者之间存在互补性,论文在图像多小波变换统计特征和视觉掩蔽模型基础上,提出了一种新颖的图像多小波变换域内基于扩频和量化的混合数字水印方案。实验结果表明所提出的算法既具有较高的嵌入容量,又具有较强的鲁棒性,特别是在高压缩比下具有较高的性能。 |

| Abstract: | Spread spectrum and quantization are two basic techniques of digital watermarking.The characteristic of spread spectrum is robust against attack and quantization watermarking allows the higher capacity.Considering both of them can complement each other,using the statistical property and visual masking model of image multiwavelet transform,this paper proposes a novel hybrid-watermarking scheme based on spread spectrum and quantization in multiwavelet domain.The experimental results demonstrate that the proposed algorithm provides higher embedding capacity as well as more robust against attack,especially at higher compression rations. |
| Keywords: | digital watermarking spread spectrum quantization muhiwavelet transform perceptual masking model |
