【 摘 要 】

In this paper, a novel algorithm for moving object tracking based on position vectors hasproposed. The position vector of an object in first frame of a video has been extracted based onselection of region of interest. Based on position vector in first frame object direction has shown innine different directions. We extract nine position vectors for nine different directions. With theseposition vectors next frame is cropped into nine blocks. We exploit block matching of the firstframe with nine blocks of the next frame in a simple feature space by Descrete wavelet transformand dual tree complex wavelet transform. The matched block is considered as tracked object andits position vector is a reference location for the next successive frame. We describe performanceevaluation and algorithm in detail to perform simulation experiments of object tracking usingdifferent feature vectors which verifies the tracking algorithm efficiency.
