Kalman filter for object tracking python

Multi Object tracking is done using Kalman Filter where we estimate the next position of a particular object using the detection in the previous frame. Once we have the prediction of the object in the next frame we associate this estimate with the actual detection and now using hungarian algorithm we assign each detection with the tracked. The Extended Kalman Filter Python example chosen for this article takes in measurements from a ground based radar tracking a ship in a harbor and estimates the ships position and velocity. The radar measurements are in a local polar coordinate frame and the filter 's state estimate is in a local cartesian coordinate frame. ...
