Digital watermarking techniques have been proposed as an effective way to protect copyright of multimedia data. From the study of general watermarking, a new algorithm of dual color images watermarking (DCIW) is presented to hide color watermark image into color images by multi_resolution wavelet decomposition . Several experiments show the good robustness of this algorithm to the common image processing,such as cropping, image compression, smoothing, zooming and so on.

在一般水印研究的基础上,提出了一种基于离散小波变换(DWT)的双彩色图像水印算法(DCIW).通过不同色彩空间的相互转换,利用二维DWT变换对图像进行多尺度分解,将彩色数字水印图像植入彩色图像中,并通过滤波过程,能将彩色水印图像完整地抽取出来.通过多项实验证明,该算法对剪切、有损压缩、平滑、放缩等操作均具有较强的鲁棒性.

Based on the frequency response characteristic and just noticeable distortion of human visual system,2-di-mensional bar code is embedded as digital water marking into the protected image through discrete wavelet transform.The problem between a great deal of information and invisibility of digital water marking is solved.At the same time the digital water marking is also robust,that is,after the image with embedded digital water marking is processed by low-pass filter or high-pass filter,the separated digital...

Based on the frequency response characteristic and just noticeable distortion of human visual system,2-di-mensional bar code is embedded as digital water marking into the protected image through discrete wavelet transform.The problem between a great deal of information and invisibility of digital water marking is solved.At the same time the digital water marking is also robust,that is,after the image with embedded digital water marking is processed by low-pass filter or high-pass filter,the separated digital water marking is almost as well as the original water marking.

根据人的视觉系统(HVS)的频率响应特性和JND特性,将二维条形码压缩编码后作为数字水印,利用离散小波变换(DWT)嵌入到被保护的数字图像中,较好地解决了二维条形码信息量大与水印隐蔽性之间的问题,同时使二维条码水印在数字图像中有很好的隐蔽性和鲁棒性;嵌入了二维条形码数字水印的图像,经过低通滤波或高通滤波都能提取很好的水印。

Blind source separation can separate or extract the source signals from mixing signals, without knowing the characteristics of the transmission channels and source signals. A new image watermark detection and extraction technique based on blind source separation was proposed. After introducing a general image watermarking embedding method in wavelet domain, the paper applies blind separation algorithms using cumulants for watermark detection and extraction in every wavelet domain.
