Description

Mat transitionMatrix; //!< state transition matrix (A)
Mat processNoiseCov; //!< process noise covariance matrix (Q)
Mat measurementNoiseCov;//!< measurement noise covariance matrix (R)

all those are public members in the c++ api, but not accessible from python or java.

but to get the extended kalman functionality, it is nessecary at least to be able to set them.

looking at the generator scripts, it seems, that member vars are ignored, so a simple setter function would do the trick(for both python and java):

CV_WRAP void setTransitionMatrix( const Mat& transition ) { transitionMatrix = transition; }
