| 摘 要： | 针对传统均值漂移(Mean Shift)目标跟踪算法中核函数带宽缺乏良好自适应调整的缺点,提出了自适应调整核函数带宽的Mean Shift目标跟踪算法.该算法首先采用核函数计算目标颜色特征值的概率密度,在视频当前帧目标的最优位置区域由目标颜色特征概率投影生成目标概率密度分布图；然后根据概率密度零阶矩值调整下一帧跟踪窗口...

| Abstract: | In this paper,a new mean-shift target tracking algorithm is proposed to improve the kernel function bandwidth-adaptive ability of the traditional one.First,the probability density of the eigenvalue of the target color is derived by employing the kernel function.Next,a distribution image of the target probability density is projected on the new optimal location of the target in the current video frame.Then,according to the zeroth-order moment of the probability density distribution,the width of the tracking ... |
