An Effective Target Tracking Method

摘要：

Target tracking system bas important application in military and civilian. In it, speed and accuracy are two important evaluations indicators. Harris algorithm is used to extract little part of target corner features which can improve this methods speed. Then, the proposed method uses optic flow method which has high matching accuracy to match those extracted corner features in the following video frames. However, when the tracked target is rotated or transformation, the distributing of matched feature point is changed and target is easily lost. In order to overcome this shortcoming, bary algorithm is used to compute the bary of those matched features as displacement of target. It is proved by experiments that this method has not only high speed and tracking accuracy but also higher robustness to target rotation, transformation, shelter etc.
