摘要
通过对分形结构的研究发现,自相似分形集具有抗几何形变的良好特性,基于此提出基于分形的空间域数字水印算法。该算法利用自相似分形对原始水印进行分形转化,再按空间域水印算法进行嵌入和提取。实验结果表明此算法具有较好的嵌入效果。
The paper applies fractal theory in the image digital watermarking,then improves a digital watermarking algothrim in spatial domain based on the fractal.Its embedding and extraction with the significance watermarking are realized,and its insufficient insutticiency is tested.Experimental results show that this method has better embedding performance.
