| 摘 要： | 提出了用于底层图像挖掘和隐藏的Zadeh—X变换方法，同时巧妙的运用了人类视觉的对比度分辨率限制（只能分辨大于5个灰度／色度级的图像成份）对图像进行隐藏和挖掘。我们首先通过图像的灰度谱，获取图像的灰度分布信息，然后用Zadeh—X变换对原始图像进行白、黑或其它背景颜色的隐藏，隐藏后的图像具有很好的伪装性。我们同样也可用Zadeh—X变换从隐藏后的图像中把原始图像不失真地恢复出来。

| Abstract: | We proposed a method of Zadeh-X transformation used in the lower layer image hiding and mining.Meanwhile the method can rather successfully hide and mine the images by virtue of the limitation of the human vision(Humen can only distinguish the parts of the image which are more than five gray or color levels).We firstly acquire the gray distribution information via gray spectrum,and then hide the image in white,black or other color background using the Zadeh-X transformation.The hidden image is well pretended.We also can retrieve the original image from the hidden image exactly. |
