基于LabVIEW平台的彩色图像数字水印系统的设计与实现

Color Image Digital Watermarking System Based on LabVIEW

采用适用于静态彩色图像的小波域水印算法,结合人眼视觉系统的特性,将一幅标识版权信息的水印图像嵌入到一幅彩色图像中,使水印具有不可见性。实验结果表明,该算法嵌入的水印具有较好的鲁棒性。利用LabVIEW和MATLAB相结合设计开发了基于虚拟仪器技术的彩色图像数字水印系统。主要用于解决当前网络信息和各种数字媒体的版权保护以及身份鉴定问题,具有积极的社会效益。

Integrating the human visual system（HVS）, employing the characteristics of mtdti-resolution analysis of the two-dimension discrete wavelet transform （DWT）,a theory scheme of an adaptive watermark embedding algorithm was proposed. Based on the theory of the algorithm the color image digital watermarking system is designed and completed by using MATLAB and LabVIEW based on virtual instrument.
