Abstract

According to characteristics of video surveillance and strong mobility of tracking targets

a novel target tracking framework based on a probability model was proposed. The current standard particle filtering target algorithm was improved based on a target appearance model

a systemic dynamic model

and a systemic observation model. Firstly

the target appearance model was established by taking the distribution of human eye cell into account to improve its resistance capability for partial occlusion of local occlusion. Then

the systemic dynamic model based on the adaptive target movement was built to improve the robustness of tracking framework for the fast moving target. Finally

the systemic observation model with online update was established to prevent the tracking shift when the target faced the occlusion

illumination changes

severe deformation

etc.

effectively. Experimental results show that the proposed algorithm achieves 98% of correct tracking rate

and the average tracking error is less than 6 pixels. The proposed method satisfies the video surveillance system require ments for stabilization

reliability

higher precision

less computing cost

as well as strong anti-jamming.
