Aiming at those problems, a time calibration algorithm based on Least-SquareCriterion is presented.
针对上述问题，提出了一种基于最小二乘准则的时间校准算法。

Then, the image grey level of every subimage is approximated by low-order polynomial according to least-squarecriterion.
然后各子图内像素灰度值以低阶多项式表示，依最小二乘准则以多项式逼近原图像的子图像。

Estimation of GM (1, 1) model parameter usually adopts the leastsquarecriterion, but test of model precision often USES average relative error criterion.
