[0092] The present invention will be further described in detail below in conjunction with specific examples, but the embodiments of the present invention are not limited thereto.
[0093] Aiming at the limitations of traditional particle swarm optimization algorithms, the present invention proposes a target tracking algorithm based on dual-center particle swarm optimization, with the purpose of realizing a stable, accurate, and anti-occlusion real-time target tracking method.
[0094] First, select the target of interest in the first frame; then calculate the image characteristics of the target area; then, apply an improved dual-center particle swarm optimization algorithm to subsequent image frames to obtain the global optimal particle position in the image frame , Namely the position of the target; finally judge whether the target is occluded, if the target is occluded, the target template update is not performed, otherwise the target template update is performed.
