flatness measurement meaning in Chinese

平面度测量

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
在空间域内，利用人的视觉特性，我们提出了基于图象方差、图象平坦测度、模糊分类的隐藏算法，同时提出了基于差值矩阵的信息隐藏。
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
在空间域内，利用人的视觉特性，本文提出了基于图象方差、图象平坦测度和基于模糊分类的隐藏算法，同时提出了基于关系、基于差值矩阵和基于密码算法的隐藏方法，并提出了备份隐藏和伪装隐藏两种隐藏方案。
