| 摘 要： | 提出了一种基于自适应四叉树分形编码的数字水印技术。对原始图像进行四叉树分形编码后，通过给定子块在不同的寻找区域中搜索其最佳匹配父块来嵌入水印。实验结果表明，本方法在嵌入水印编码时间、图像质量和鲁棒性方面均比传统的方法有较大的改进。

| Abstract: | This article introduces a digital watermarking technology based on adaptive quadtree fractal coding.After the original image is maked to quadtree fractal coding,we embed watermarking into it by range blocks searching its most-matched domain blocks in different search regions.Experimental results showed that the proposed method is advanced than the traditional method at the coding time of watermaking embedding,image quality and robustness. |
