融合人群密度的自适应深度多目标跟踪算法

多目标跟踪技术不能较好地解决目标严重遮挡场景下的多目标跟踪问题,因此文中提出融合人群密度的自适应深度多目标跟踪算法.首先,融合人群密度图和目标检测结果,利用人群密度图的位置和计数信息修正检测器结果,消除漏检、误检.然后,使用自适应三元组损失改进行人重识别模型的损失函数,提高对重识别特征的辨别能力.最后,使用外观和运动信息进行目标关联,得到最终的跟踪结果.实验验证文中算法可有效解决目标严重遮挡场景下的多目标跟踪问题.

Adaptive Deep Multi-object Tracking Algorithm Fusing Crowd Density

Multi-object tracking technology cannot well solve the problem of multi-object tracking in the scenarios with objects severely occluded, and therefore an adaptive deep multi-object tracking algorithm fusing crowd density is proposed. Firstly, the crowd density maps and object detection results are fused, and the location and the count information of crowd density maps are utilized to correct the detector results to eliminate missing and false detections. Then, adaptive triplet loss is employed to improve the loss function of the re-identification model and thus the discrimination of the algorithm for the re-identification feature is enhanced. Finally, final tracking results are obtained using the appearance and motion information for objects association. It is verified through the experiments that the proposed algorithm effectively solves the problem of multi-object tracking in severely occluded scenes.
