For many applications like robotics, autonomous driving, or smart factories, machines have to be aware of humans in their vicinity. This requires to know the location and pose of the present humans and track them continuously. Although person detection, person reidentification and pose tracking are highly correlated, the three tasks have been previously studied independently. For instance, the alignment quality of the bounding boxes of detected persons affects the re-identification accuracy. If a person is occluded for a long time or re-appears after leaving the scene, it needs to be re-identified. Furthermore, person detectors struggle to detect partially occluded persons whereas visible joints can be detected even if other parts of the human body are occluded. We will therefore investigate how the three tasks can assist each other and we aim to improve the accuracy for all three tasks by solving them together in a joint framework.

对于机器人、自动驾驶或智能工厂等许多应用，机器必须了解附近的人类。这需要知道当前人类的位置和姿势并持续跟踪他们。尽管人员检测、人员重新识别和姿势跟踪高度相关，但这三个任务之前已经被独立研究过。例如，被检测人员的边界框的对齐质量会影响重新识别的准确性。如果一个人长时间被遮挡或者离开场景后再次出现，就需要重新识别。此外，人体检测器很难检测到部分被遮挡的人，而即使人体的其他部分被遮挡，也可以检测到可见的关节。因此，我们将研究这三个任务如何相互协助，我们的目标是通过在联合框架中一起解决这三个任务来提高所有这三个任务的准确性。
