| Abstract: | Digital watermarking based on Singular Value Decomposition(SVD) is a kind of transform domain watermarking which is worth researching,and brings new ideas and methods into the field of digital watermarking.In this paper,we will conduct in-depth analysis and research on the traditional digital watermarking technology based on SVD.In addition,we are going to propose the improved methods,and a new algorothm on the digital watermarking technology.Experiments demonstrate that this new scheme is invisible and rob... |
