卵形构造是由紫苏花岗岩固态气球膨胀侵位形成的，之后又受到深部构造相韧性变形带的叠加，使卵形构造由东到西受改造的程度逐渐增大。

Imperceptibility of steganography based on structural similarity function;

基于构造相似性的不可感知性评价指标

Based on subjective image quality methods and human visual system (HVS), the structural similarity function (SSF) is first introduced into the practical steganography evaluation to balance the fault and limitation of traditional objective methods—peak signal to noise ratio (PSNR).

为了评价信息隐藏技术,建立正确、全面的不可感知性指标,在研究主观评价及人眼视觉特性基础上,分析传统图像质量评价指标峰值信噪比(PSNR)的缺陷和不足,并首次引入构造相似性函数(SSF)作为不可感知性评价指标。
