A fast algorithm avoiding the calculation of correlation coefficients is applied to the pattern tracking for an airflow measurement. The pattern similarity is defined by the reputation number of the summations of gray level difference between corresponding pixels until the accumulation exceeds a critical value. An example of the sensitivity examination of parameters included are also described.
