Template matching tracking method based on particle swarm optimization

Abstract

The invention discloses a template matching tracking method based on particle swarm optimization. The method comprises the steps of firstly predicting the position where a target is possibly located in a current frame according to movement conditions of the target in the past, wherein each type of prediction is represented by a particle in a particle swarm optimization algorithm, and the position and the range of the target are used to act a searching space of the particle swarm optimization algorithm; and secondly, searching a target state value with the maximum correlation matching value in a state searching space by using a particle swarm optimization searching algorithm to act as a result of target tracking, and adaptively updating a template according to the tracking result so as to realize continuous and steady tracking. According to the invention, the particle swarm optimization searching method is adopted to search in the target state space, and target template matching is carried out so as to acquire the tracking result of the current frame. The method disclosed by the invention can well improve the robustness of a tracking algorithm, and greatly reduces the complexity of the algorithm.
