A Tracking Methods of Aerial Target Based on the Image Sequences

文中提出一种有效的运动跟踪检测算法对空中运动目标进行快速、准确的检测和跟踪,首先利用对称图像差分梯度法进行运动目标检测,该方法能很好地检测出移动背景中低信噪比的运动目标;然后通过改进的活动轮廓模型在视频图像序列中进行跟踪,实验结果表明,使用该方法可以得到有效的目标轮廓,从而获得准确跟踪效果。

In this paper,we proposed an effective tracking algorithm to achieve rapid and precise detection and tracking for aerial target.Firstly,symmetry difference gradient operations is used to detect moving object,which can detect moving object with low SNR from movable background effectively;In addition,improved active contour model is used to keep track in video sequence.Experiment results proved that this method is effective to get the contour of the target, thus achieve accurate result of tracking.
