针对现有的粒子滤波跟踪方法存在的不足,提出了一种改进的粒子滤波器方法用于运动目标跟踪.将颜色直方图和边缘直方图结合起来建立目标的参考模型,有效地克服了使用单一特征建模的缺点,提高了跟踪的准确性.分别计算目标颜色模型和目标边缘模型与粒子的欧几里德距离,使用这2个距离作为粒子权值计算的重要依据.实验结果表明该算法具有较高的实时性、准确性和鲁棒性.

The op timal design of stack filters is actually an op timization of a positive Boolean function. In order to speed up the op timizing rate and p roduce a global op timal design of the stack filters, an imp roved clonal selection algorithm ( ICSA) is p resented, which introduces a polyclonal operator and simultaneous evolution of the memory u2 nit and the reserved group. The number of clonal particles in the memory unit can adap tively change with their af2 finity concentration. Regroup ing operations are made between parent generations and child generations in the mem2 ory unit, avoiding p roblems caused by breeding two close particles. The p reservation of group mutations guarantees diversity. Our experimental results confirmed that stack filters op timized with ICSA p roduce better filtering results in less time.
