Or, at a much higher cost of collection, it's possible to calculate an approximation of the percentage of overall CPU resources consumed by the thread for an execution.
或者，如果收集成本特别高的话，可以计算线程在执行时占用CPU资源的百分比的近似值。

Another method is thin plate spline elastic approximation, which takes the overall smoothness of the whole image into account, hence it is better when errors of feature points exist.
而弹性近似法充分考虑了整体平滑性的要求，对定位有误差的标志点约束的图像配准更为优越。

The difference approximation is called the partial discretization method, and the overall fitting the overall discretization method.
