摘要
本文提出了一种基于复小波变换的新的具有鲁棒性的数字图像水印方法。为了改进算法的鲁棒性,本文采用了纠错码,该技术是在空域中进行的。为了了解本文所提出的在CWT域上所提出的算法,我们在DWT域上采用同样的嵌入算法来和它进行比较。最后,我们要通过试验来检测两种算法对于选择性攻击(比如JPEG,JPEG2000压缩)的鲁棒性,并利用水印检测软件基准来对他们进行比较。
A new digital image watermarking method based on complex wavelet transform was presented in the paper. In order to improve its robustness feature in the algorithm, the Error Correction Code is used., the technique is performed in spatial domain. To compare the proposed algorithm in CWT domain with equivalent on derived in the DWT domain, the same embedding procedure in applied in DWT domain. Robustness of both algorithm on selected attacks like JPEG, JPEG2000 compressions, different filtering attacks etc. is tested and compared by using the benchmark software Checkmark.
