In spatial domain , according to the characteristics of hvs ( human visual system ) , we introduce several approachs based on images " deviation , images " flatness measurement , fuzzy classification , and an approach based on difference matrix as well 在空間域內(nèi),利用人的視覺特性,我們提出了基于圖象方差、圖象平坦測度、模糊分類的隱藏算法,同時提出了基于差值矩陣的信息隱藏。
According to the feature of the human vision , we present the hiding methods based on image variance , image flatness measurement and fuzzy classification , respectively . and the techniques based on relationship between pixels , difference matrix and cryptography are also given . two hiding methods , backup hiding and camouflage hiding , are proposed too 在空間域內(nèi),利用人的視覺特性,本文提出了基于圖象方差、圖象平坦測度和基于模糊分類的隱藏算法,同時提出了基于關(guān)系、基于差值矩陣和基于密碼算法的隱藏方法,并提出了備份隱藏和偽裝隱藏兩種隱藏方案。
