Digital Image Blending Technology Based on Ploya Model
基于Ploya模型的数字图像融合技术*

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.
