【摘要】 将算子引入外逆P-集合的研究中,拓宽逆P-集合的应用领域。把外逆P-集合的理论应用于数字图像的信息伪装研究,建立了f信息伪装、g信息伪装、双信息伪装以及信息伪装度量的概念。给出了信息伪装度量性质定理、f信息伪装-还原定理、g信息伪装-还原定理以及数字图像的双信息伪装-还原定理。最后给出了应用实例。更多还原

【Abstract】 This paper first introduced operator into study of outer inverse P-sets and broaden the application of inverse P-sets.Then the theory of outer inverse P-sets was applied in information camouflage of digital image,and the concepts such as f-information camouflage,g-information camouflage,double information camouflage and information camouflage metric were established.The information camouflage metric property theorem,f-information camouflage-recovery theorem,g-information camouflage-recovery theorem of digital image and double information camouflage-recovery theorem of digital image were proposed.Finally,the application example was given.更多还原
