摘要
提出了一种在空间域对数字图像进行融合的隐藏技术。该算法利用Ploya概率模型 ,由多幅图像对一幅秘密图像进行隐藏。为了降低图像融合中的数据膨胀 ,考虑由少量公开图像产生多幅图像 ,计算机实验显示该算法能较好地用于图像隐藏 。
Aiming at ensuring digital image information security,a new digital image blending scheme in spatial domain based on Ploya probabilistic model is presented.With the scheme a secret image can be hidden in many images which can be generated from a few public images,this solves the problem of images data expanding.Experimental results show that the algorithm has satisfying effect for image hiding with certain robustness.
