The certainty measurement of object feature is defined by using spatial distribution and observation probability of particle.The measurement is introduced into the object tracking algorithm based on multi-feature fusion,and the weighted value of object feature is adjusted adaptively.So the object feature can adaptively adjust its contribution to tracking in different scenes and external disturbance.The results of the experiment show that the algorithm based on certainty measurement is more robust than traditional algorithm using single feature or multi-feature fusion with fixed weighted value.
