Mean Shift算法运用在运动目标跟踪时,首先根据目标特征的概率直方图建立初始模板,一般选取目标的颜色特征,为了使跟踪效果更好,也会选择多种特征的结合;然后在当前帧中选择以前一帧的目标真实位置点为中心,以固定设置的Mean Shift搜索半径为半径的区域建立候选目标模板;再对两模板进行相似性度量。如果没满足预设要求,则以...
下图是我在一张图上面实现的迭代shift,首先选中一块目标区域,计算好目标直方图,然后将候选区域从目标区域的位置平移一段距离,执行meanshift算法,结果候选区域慢慢收敛到了目标区域,图上绿十字代表整个shift的轨迹。这就是跟踪的基础了,把在同一张图上执行meanshift改为在连续两帧图像上执行就可以实现跟踪了。 多目标跟...

Mean-Shift tracking gained a lot of popularity in computer vision community. This is due to its simplicity and robustness. However, the original formulation does not estimate the orientation of the tracked object. In this paper, we extend the original me
尺度自适应一直是跟踪算法的难点,在Mean Shift跟踪中解决尺度问题一般从推导过程进入,所以这类文章的数学推导略难: [4] Robert T. Collins.Mean-shift blob tracking through scale space. CVPR, 2003. [5] Zoran Zivkovic, Ben Krose.An Em-like algorithm for color-histogram-based object tracking. CVPR, ...

A motion detection process is also performed to avoid the target centers' erroneously shifting to color similar static background when no motion exists. Representative experiments validate that the proposed method improves the accuracy of mean-shift tra...
