Detailed Description

Extended Kalman Filter (EKF) implementation.

Please override the pure virtual f() with the desired unlinear function. By default the upate_F calculates the Jacobian numerically, if you want other approach override also the update_F()

Examples:
SampleFilter.cpp.

Member Function Documentation

virtual void alvar::KalmanEkf::f ( CvMat *  _x,
CvMat *  _x_pred,
double  dt 
) [protected, pure virtual]

Implemented in KalmanOwn.

void alvar::KalmanEkf::predict_x ( unsigned long  tick) [protected, virtual]

Reimplemented from alvar::KalmanCore.

Definition at line 276 of file Kalman.cpp.

void alvar::KalmanEkf::update_F ( unsigned long  tick) [protected, virtual]

If your transition matrix F is based on time you need to override this method.

Reimplemented from alvar::Kalman.
