چکیده: Abstract: The tracking algorithm is an important tool for motion analysis in computer vision. A

new car tracking algorithm is proposed which is based on a new clipping technique in the field

of adaptive filter algorithms. The uncertainty and occlusion of vehicles increase the noise in

vehicle tracking in a traffic scene, so the new clipping technique can control noise in prediction

of vehicle positions. The authors present a new quantised version of the LMS, namely the

QX-LMS algorithm, which has a better tracking capability in comparison with the clipped LMS

(CLMS) and the LMS and also involves less computation. The threshold parameter of the

QX-LMS algorithm causes controllability and the increase of tracking and convergence properties,

whereas the CLMS and LMS algorithms do not have these capabilities. The QX-LMS algorithm is

used for estimation of a noisy chirp signal, for system identification and in car tracking

applications. Simulation results for noisy chirp signal detection show that this algorithm yields a

considerable error reduction in comparison to the LMS and CLMS algorithms. The proposed

algorithm, in tracking some 77 vehicles in different traffic scenes, shows a reduction of the tracking

error relative to the LMS and CLMS algorithms.
