Sobel operator and gray square centrobaric arithmetic were synthesized with the improved SUSAN operator in subpixel corner detection.
在利用改进的SUSAN算子进行亚像素角点检测时，综合应用了索贝尔边缘算子、灰度平方重心法等方法。

Finally, the method of triangle is compared with energy centrobaric correction method, with the conclusion that noise has less effects on the method of triangle.
最后将三角形法和能量重心法进行了对比，得出了三角形法受信噪比变化影响较小的结论。

The centrobaric method was used to determine the position with the maximum modulation value of fringes and the position was used as the point of zero light path difference.
