DIPSO incorporates the dynamic mutation, multi-subpopulations methods of IPSO, and changes the heights and the positions of the peaks by variable parameters and chaotic model. This algorithm uses multi-subpopulations to search for the highest peak in order to track the dynamic environments. Furthermore, DIPSO apperceives the changes of the environment by tracking the fitness value of the global optimal particle.

该算法是IPSO的动态版本，沿用了IPSO的动态变异策略、多子种群策略，在算法运行的过程中分别对环境进行参数设定型动态变化和混沌模型动态变化，利用多子种群分别对多个峰进行搜索，很好地实现了算法的追踪性能；对全局最优粒子进行实时跟踪，利用其适应度值的变化来发现环境的改变，并以此来引导群体对环境变化的感应。

Since Gabor feature is robust to illumination and expression variations and has been successfully used in face recognition area. First, the proposed method decomposes the normalized face image by convolving the face image with multi-scale and multi-orientation Gabor filters to extract their corresponding Gabor magnitude maps. Then, the local binary patterns operates on each GMM to extract the local neighbor pattern. Finally, the input face image is described by the histogram sequence extracted from all these region patterns.
