| 摘 要： | 针对结合混沌映射和多重混合的数字图像水印嵌入及提取问题,提出利用迭代学习辨识算法提取水印图像的方案。该方案将水印掩盖于混沌系统的参数中,以迭代学习算法重建原始水印图像。实验表明,运用所提出的迭代学习辨识算法能够从含水印图像中提取出完整的水印图像,给出的测试结果验证了学习算法抵抗常见几何攻击的能力。

| Abstract: | This paper presents a digital image watermarking scheme based on chaotic mapping and multi-blending,and the decryption and extraction of the digital watermark is carried out from iterative learning identi?cation perspective.With the proposed scheme the watermark image is added to a parameter of the chaotic system undertaken,and the mechanism of multi-blending is used for generating the final image,which aims to enhance watermarking security.An iterative learning identification algorithm is proposed for the ... |
