The algorithm tracks the changing rate of each coordinate transformation parameter through Kalman filter to facilitate better prediction of the initial searching point. More importantly, the powers of the noise models of the Kalman filter are effectively estimated online rather than making artificial assumptions on their values. The algorithm can hence adapt to various target motions and searching precisions in a real-time manner without any manual intervention.
