Between 3.0 K and the triple point of neon (24.5561 K) T90 is defined by means of a helium gas thermometer calibrated at three experimentally realizable temperatures having assigned numerical values and using specified interpolation procedures.

ITS-90划分了几个主要温区和附属温区，并对每个温区的温度T90 给出了详细的规定。这些温区之间有重叠交叉部分，当重叠区域出现T90定义不唯一的情况时，两种定义同等适用。

In this algorithm, phase correlation was used to estimate the overlapping area, in which Harris corner detector was used to extract feature points, and then a pseudo matching set was obtained. These pseudo matches were divided into inliers and outliers by using robust RANSAC algorithm.

此算法首先使用相位相关法估计平移参数并初步确定重叠区域，在重叠区域采用Harris角点检测算法进行特征点提取得到初步的伪匹配集合，并运用稳健的RANSAC算法将伪匹配点集合划分为内点和外点。
