摘　　要：以数字图像信息隐藏问题为研究的切入点,介绍了奇异值的数学理论基础,讨论了矩阵奇异值分解与重构的原理和方法;构造了一种新的基于奇异值分解的图像隐藏的算法,用实例说明了奇异值分解在图像隐藏中的原理和应用,并在奇异值分解的基础上重构了原图像,取得了较好的效果,表明了该方法的有效性.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.
