Abstract: To achieve the fast extracting and steady tracking of an arbitrary target in the complex environment, a new method of constituting and updating target template was proposed. Using an adaptive spacial filter to partition the target area, then the target is extracted using twoprojection method,and the template is updated according to its evaluation function during tracking. The proposed method is characterized by good adaptability of the template, exact judge of the target, and good tracking robustness. The field experiment shows that when target is changeable or covered by other objects, the system can still extract the target exactly and keep tracking steadily.
