Step finds the exact position for having found shake point, and detailed process is as follows：
1）Determine the relevant parameter of algorithm：Length of window W, threshold value M；
2）A certain location point X is determined, the preceding W point for making X is that window A, X rear W point are window B；
3）Judge in window B size a little with M, if the value of certain point is more than M values, with the M values replacement point
Value, and calculate sum a little；With same method
Calculation window A sum a little.Then the average ratio of B windows and A windows is calculated
Mobile X position, recalculates this ratio, finally gives one group of sequence of ratio values；
4）Value maximum in this sequence is traveled through, and reduces corresponding X points position.
