When using multi-frame image to extract target, image morphological dilation is used firstly to accumulate multi-frame image effectively and then associate the track with image flow method.

在利用多帧图像进行目标提取时，针对多帧图像积累的有效性保证问题，采取了在积累前进行图像形态膨胀的方法，通过图像流法进行多帧图像航迹关联。

This method accumulates the energy in the multi-frame image data along the target trajectories, and chooses a target trajectory whose accumulation value is biggest from all possible trajectories.

这种方法在多帧图像数据中沿着目标轨迹积累能量，在多条可能的轨迹中，选择积累值最大的一条作为目标轨迹。
