Image Centroid Tracking Using Square Root Information Filter
Determination of a moving target’s position and velocity from a noisy time-series of images captured by
imaging sensors constitute a classical statistical estimation problem. Often the covariance based centroid tracking Kalman
filter (KF) is used for target tracking purpose. In this paper, the information based centroid tracking filter called square root
information filter (SRIF) is presented for centroid tracking of a target. A MATLAB code for SRIF is developed. Some
simulation results are presented.
