| Abstract: | 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 qualif ied 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. |
