实现基于压缩感知的数字图像水印算法,主要包括水印嵌入、水印提取及子程序三大部分。水印载体图像和原水印图像使用者可以自行更改。(This program functions for the realization of compression based digital image watermarking algorithm, including watermark embedding, watermark extraction and subroutines three major parts. The watermark carrier image and the original watermark image can be changed by the user.)
As an effective method on copyright protection of digital media , Watermarking technology referrs to many subjects ,thus needing a strong
research tool. MATLAB has a lot of advantages itself, and is qualifi ed for watermarking research.. This paper introduces the common concept through
which digital watermarking is implemented and proposes a image digital watermarking algorithm based on the wavelet lifting. Simulation results show
that the scheme can handle it quikly and embedded watermarking has the characteristics of abundant information and better invisibility.
