【摘要】 针对视频多目标跟踪中由于目标间的遮挡、交错或目标漂移而导致跟踪失败的情况,提出一种基于卡尔曼滤波以及空间颜色直方图的遮挡预测跟踪算法。利用空间颜色直方图对目标进行建模,可以对不同目标进行区分进而在目标之间出现交错或目标漂移时仍能跟踪到目标。通过卡尔曼滤波算法可以预测目标的状态,对预测位置之间存在交错的目标进行遮挡标记,以便在下一帧中仍然可以跟踪到被遮挡的目标。采用2D MOT 2015数据集进行实验,跟踪的平均精度达到了34.1%。实验结果表明,所提方法对多目标跟踪的效果有所提高。更多还原

【Abstract】 Aiming at the tracking failure caused by occlusion between objects,interleaving or target drift in multi-object tracking,this paper proposed an occlusion prediction tracking algorithm based on Kalman filter and spatiograms.By combining the color histogram and the distribution of color in space,spatiograms can be used to distinguish different objects,so that the object can still be tracked when interleaving or occlusion between objects occurs.The state of the object can be predicted by the Kalman filtering algorithm.The occlusion mark is used for the object which overlaps with other objects,so that the occluded object which is undetected can be tracked in the next frame.The 2D MOT 2015 data set was used for experiment.The average accuracy of tracking achieves 34.1%.Experimental results show that the algorithm can improve the performance of multi-object tracking.更多还原
