利用結(jié)構(gòu)模板對(duì)運(yùn)動(dòng)目標(biāo)進(jìn)行跟蹤
Tracking Moving Object with Structure Template
-
摘要: 該文提出了一種運(yùn)動(dòng)目標(biāo)的兩步跟蹤算法。該算法首先利用形態(tài)學(xué)方法得到目標(biāo)的結(jié)構(gòu)模板,再利用結(jié)構(gòu)模板完成對(duì)目標(biāo)的跟蹤。結(jié)構(gòu)模板由目標(biāo)圖像中能夠反映目標(biāo)基本結(jié)構(gòu)信息的穩(wěn)定的邊緣和交叉點(diǎn)構(gòu)成。跟蹤過程分為兩步:第一步先把結(jié)構(gòu)模板調(diào)整到要跟蹤的目標(biāo)附近;第二步作精細(xì)調(diào)整使結(jié)構(gòu)模板發(fā)生形變,收斂到目標(biāo)圖像中的交叉點(diǎn)和邊緣處。由于在跟蹤過程中考慮了目標(biāo)的整體結(jié)構(gòu)信息,利用這種方法可以大大提高跟蹤的穩(wěn)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. -
