摘要
本文对matlab数字水印技术做了简要的介绍,并对matlab数字水印技术的应用和实现图像版权保护的方法等要素进行了探讨。同时以基于DWT算法来实现数字水印的嵌入为例。通过对以小波变换为基础的数字水印算法所嵌入水印的图像进行剪切,旋转,噪声等攻击,并在其峰值信噪比和相似度两个方面进行定量分析。
this paper made brief introduction to matlab digital watermarking technology and matlab application of digital watermarking technology and method of digital image copyright protection and other factors are discussed. Both dwt-based digital watermarking algorithm to embed,for example. Based on wavelet transform for digital watermark embedding algorithm based on image for cropping,rotaing,noise and other attacks,and at its peak signal to noise ration and quantative analysis of the similarity between the two.
