The three-stage human brain memory model is incorporated into a multiagent coevolutionary process for finding the best match of the appearance of an object, and a memory-based multiagent coevolution algorithm for robust tracking the moving objects is presented in this paper. Each agent can remember, retrieve, or forget the appearance of the object through its own memory system by its own experience. A number of such memory-based agents are randomly distributed nearby the located object region and then mapped onto a 2D lattice-like environment for predicting the new location of the object by their coevolutionary behaviors, such as competition, recombination, and migration. Experimental results show that the proposed method can deal with large appearance changes and heavy occlusions when tracking a moving object. It can locate the correct object after the appearance changed or the occlusion recovered and outperforms the traditional particle filter-based tracking methods.
将三阶段人类大脑记忆模型纳入多智能体协同进化过程,以寻找物体外观的最佳匹配,并提出了一种基于记忆的多智能体协同进化算法用于稳健跟踪运动物体。每个智能体可以通过自身的记忆系统,根据自身经验记住、检索或忘记物体的外观。多个这样基于记忆的智能体随机分布在目标定位区域附近,然后映射到二维晶格状环境中,通过它们的协同进化行为(如竞争、重组和迁移)来预测物体的新位置。实验结果表明,该方法在跟踪运动物体时能够处理较大的外观变化和严重遮挡情况。在物体外观改变或遮挡恢复后,它能够定位到正确的物体,并且性能优于传统的基于粒子滤波器的跟踪方法。
