WebbThe Kalman filter will try to update the mean and the covariance using the input detections. The common terminology is to call this distribution the system state. In our example, we will use the following initial state: The mean position μ_x is taken from the x position of the first detected bbox, and we are assuming some initial velocity μ_v.
