A swarm-intelligence based algorithm for face tracking
Yuhua Zheng, Yan Jing Meng · International Journal of Intelligent Systems Technologies and Applications · 2009
This article presents a new face tracking algorithm that employs a swarm-intelligence based method particle swarm optimisation (PSO). Firstly, all potential solutions are projected into a high-dimensional space where particles are initialised. Then, particles are driven by PSO rules to search for the solutions. The face is tracked when the particles reach convergence. Furthermore, a multi-feature model is also proposed for face description to enhance the tracking accuracy and efficiency. The proposed model and algorithm are object-independent and can be used for any free-selected object tracking. Experimental results on face tracking demonstrate that the proposed algorithm is efficient and robust in visual object tracking under dynamic environments with real-time performance.
