I am new to particle filtering. I can see when particle filters are used with Ensemble Kalman's, the velocity of the states are taken care of by the Kalman.
When tracking using particle filters only with position-only measurements, how do you get the velocity for propagating the particle by the transition function ? In Kalman filters, the filters smooth through the difference in position measurements. I don't see that in particle filters. Wondering if you provide velocity as a pseudomeasurement by differencing successive measurements ?
Thanks for any help
