该算法首先通过对边缘密度图进行投影分析进行自顶向下的粗定位，然后在此基础上利用垂直边缘的连接强度进行自底向上的精确定位。

The algorithm first makes a top-down coarse location using the projection analysis of the edge density graph and then makes a bottom-up precise location based on the vertical edge linkage intensity.

分析和实验表明，该算法抗干扰能力强，对复杂背景及不重叠物体，可以精确定位并提取出各个运动目标的外轮廓。

The experiments show the high efficiency of this algorithm for contours extraction of moving objects from color image sequence with complex background.
