Kalman filter(fixed point version) In this implementation of tracking a ball, we will track a live ball using Kalman filter. The tracking will switch to autorun mode when the sight of the ball is lost and Kalman will estimate the motion based on it's previous statesThere are two models. One model is a simple simulation of the...
