摘要
图像隐藏技术作为一种常用的信息保密技术,通过将秘密图像隐藏于一幅或多幅公开图像中,来实现对秘密图像的保护。方法给出了一种邻近均值图像插值(NMI)的方法并将该方法应用于图像隐藏。邻近均值插值具有低时间复杂度和高的计算效率。结果与结论数值试验表明该方法的隐藏能力较大,并保证了很好的视觉质量,且算法简单易行。
Digital image hiding is to conceal the existence of secret Information. Methods This paper proposes a new interpolation and an information hiding method. The proposed scaling - u Pneighbor mean interpolation method has a low - time complexity and high - calculation speed. The proposed Information hiding method is based on interpolation. Comparison on Information hiding methods is divided into reversible or not. Results Conclusion Our experimental results show the proposed method can embed a large amount of secret Information while keeping a very high visual quality.
