    Abstract

    Image registration and Kalman filter based object tracking algorithm is presented. Image registration algorithms viz., sum absolute difference (SAD) and normalized cross correlation (NCC) algorithms are used to find the centroid of the object of interest and Kalman filter is used to track the centroid of the target. Paraboloid interpolation has been used to compute the centroid in sub pixel accuracy. It was observed that in presence of salt and pepper noise, the SAD algorithm performed better and in presence of Gaussian noise, the NCC performed better.
