利用结构模板对运动目标进行跟踪
Tracking Moving Object with Structure Template
-
摘要: 该文提出了一种运动目标的两步跟踪算法。该算法首先利用形态学方法得到目标的结构模板,再利用结构模板完成对目标的跟踪。结构模板由目标图像中能够反映目标基本结构信息的稳定的边缘和交叉点构成。跟踪过程分为两步:第一步先把结构模板调整到要跟踪的目标附近;第二步作精细调整使结构模板发生形变,收敛到目标图像中的交叉点和边缘处。由于在跟踪过程中考虑了目标的整体结构信息,利用这种方法可以大大提高跟踪的稳定性。

Abstract: A two-step approach for tracking moving object is proposed in this paper. According of this approach, the structure template of object is firstly extracted with morphologic methods, and then the object tracking is performed with the structure template. The structure template is composed with the stable edges and the cross-points, which can describe the essential structure information of objects. The tracking processing can be divided into two steps: in the first step, the structure template is wholly moved very closed to the tracked object, and in the second step, the structure template is modified to converge to the cross-points and the edges in object image. Because of considering the structure information of object, the robusticity of tracking can be improved greatly. -
