| 摘 要： | Mean shift算法是一种非参数密度估计算法,可以实现快速的最优匹配。为了有效地将Mean shift算法应用到灰度图像中,使用空间分布和纹理信息作为匹配信息,提出了一种基于空间方向直方图的Mean shift跟踪新算法。利用卡尔曼滤波器来获得每帧目标的起始位置,再利用Mean shift算法得到跟踪位置。实验结果证明,该算法在目标运动较快,目标尺度变化的情况下仍能稳定、实时、高效地跟踪目标。

| Abstract: | The Mean shift algorithm is a nonparametric density estimation method.The fast and optimal mode matching can be achieved by this method.In order to apply Mean shift algorithm on gray-level image effectively,a new tracking algorithm of Mean shift based on orientation histogram is proposed.It uses space spread and vein as matching information.The starting position of target is found with Kalman filter in every frame,and then Mean shift is utilized to track the target position.In the situation of target moving fast and changing of size,experiment results show that the object can be tracked steadily,effectively and real-time by using the proposed algorithm. |
