This paper proposes a method of line fitting by Fourie descriptor by which overlapped and curved pathlines in separated flow around a circular cylinder are excluded, and line fitting is applied to the remaining pathlines. Further more, this method is applied to the measurement of the length of the formation region, and it is shown that results obtained are in agreement with the other experimental ones.
