A new method for measuring velocity field by tracking particles is proposed. Kalman's filtering theory and the Chi-square test are applied to the algorithm. By using Kalman's filtering theory, the particle information at the (t+1)-th step is estimated by particle information at the t-th step. The Chi-square test is applied to correlate a particle image in the t-th frame with the same one in the (t+1)-th frame.
