摘要:
在变换域添加的数字水印一般在具有较高鲁棒性的情况下,嵌入容量都比较小.为了提高数字水印的鲁棒性和嵌入信息量,采用在不同变换域添加双重数字水印的方法.在DCT域采用修改DCT系数的方法添加了二值水印,而在DWT域采用迭代混合技术添加了灰度图像以提高水印容量和鲁棒性.实验结果表面,这一算法对JPEG压缩,剪切,加噪都具有较好的鲁棒性,很好地实现了数字水印鲁棒性和大容量的统一.
Abstract:
Watermarking embedded in transformation domain ofen possesses excellent robust performance butsmall embedding information volume, Dual digital watermarkings were embedded in diferent transformationdomains in order to improve the robust performance of the watemarking and embedding information volume. Ahinary watermarking was embedded in the DCT domain by exchanging the DCT coefficient while a gray levelimage was embedded in the DW’T domain with iterative blending technique which is ready to enlarge the vol.ume of watermarking information. It was shown that the algorithm could improve the robust performance whenit was attacked with JPEG compression , cutting and adding some noises and the embedding information volumebeing enlarged.
