| Abstract: | The article points to the research of digital image information hiding, introduce the mathsmatical theory base of singular value decomposition, discussed the theory and method of matrix singular value decomposition and reconstruction. Construct a new digital image information hiding method based on singular value decomposition, experimental result show the theory and application of singular value decomposition in digital image information hiding.Also reconstruct the original image based on singular value decomposition, gain preferably effec,indicate the validity of the new method. |
