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。
A new centre-extracted method that combined the alterable direction template with barycenter method was proposed for the implementation of real-time image processing. 基于此，提出了一种把可变方向模板和灰度重心法相结合，并充分发挥两者优点的方法。
