| 摘 要： | 本文提出了一种实时跟踪算法,以目标中心距离加权的灰度图像作为模板,采用mean-shift迭代方法实现目标的空间定位;同时建立二值图像模板,根据目标的图像特征,进行尺度定位.本算法改进了kernel-based算法对变尺度目标的跟踪.对于超过一定像素的较大目标,本算法进行"降采样",大大减小运算量,从而实现了对大尺度目标的实时跟踪.实时视频流的跟踪实验验证了该方法的有效性.

| Abstract: | A real-time image tracking algorithm is proposed in this paper.This algorithm gives small weights to pixels farther from the object center and uses the quantized image gray scales as a template.It gets the target's location by mean-shift method and gets the target's scale using image feature recognition.It improves the kernel-based algorithm in tracking scale-changing targets.A decimation method is proposed to track large size targets.Real-time experimental results verify the effectiveness of the proposed algorithm. |
