Class KalmanFilter

  • public class KalmanFilter
extends java.lang.Object
    Kalman filter class. The class implements a standard Kalman filter <http://en.wikipedia.org/wiki/Kalman_filter>, CITE: Welch95 . However, you can modify transitionMatrix, controlMatrix, and measurementMatrix to get an extended Kalman filter functionality. Note: In C API when CvKalman\* kalmanFilter structure is not needed anymore, it should be released with cvReleaseKalman(&kalmanFilter)
