Singular Value Watermarking Algorithm Based on Block-SVD
Hean Liu · Journal of Hunan City University · 2011
With the development of the digital technology,information hiding technology is valued.The digital watermarking as an important means of copyright protection has been widely research and application.This paper proposes a new based on Block-SVD of the watermarking algorithm is proposed,using the singular value decomposition method and combining with the image block technology,completed the watermark embedding and extracting.Through the image block,it reduces the singular value decomposition of image of the process,to accelerate the digital image watermarking embedding and extracting,finally with VC++ is realized the process,and shown that the proposed algorithm is robust.
