| 摘 要： | 相似目标间的遮挡一直是多目标追踪问题中的难点。针对这个问题提出了联合轮廓法。这种方法在使用粒子滤波器的基础上,通过对遮挡目标集的外轮廓建模来确定处于遮挡关系中目标的状态,从而进一步得到目标的轨迹。算法在实验中显示了良好的鲁棒性,并且计算复杂度与遮挡目标的个数成二次多项式关系。

| Abstract: | Tracking multiple similar objects is a challenging task,expecially in resolution,because of occlusion between objects.The Joint Contour Method(JCM) based on the particle filter is proposed to solve the problem of partial occlusion in this paper.It is a method to determine the object status by modeling the contour of the set of objects in occlusion.The computational complexity of JCM increases second-degree polynomially with the number of objects.The experiments demonstrate the robustness of the method. |
