摘要
介绍数字水印技术的基本原理,详细论述基于最低有效位数字水印技术的实现过程,结合实际应用提出改进方案,通过Matlab实验给出同一载体图像嵌入不同容量水印后图像的PSNR值,得出了水印容量和鲁棒性相互制约的重要结论。实验证明了方案的可行性,最后指出这种技术的局限性。
The basic principle and technique of digital watermarking are introduced. The implementing process of watermarking technique based on LSB is discussed,improved method is proposed, which is relative to practical application. Different PSNR values from the same cover image with different watermark image are shown. An important conclusion is found, which is watermark capacity and rubustness are conflict. The experiment proves the way is feasible. Localized feature is indicated.
