multiple objects tracking 比赛

多目标跟踪比赛是一项涉及计算机视觉和人工智能技术的竞赛活动。在该比赛中，参赛者需要设计和实现算法，来实现对于多个不同对象的准确识别和跟踪。

多目标跟踪是计算机视觉中的一个重要问题，其应用广泛。例如在视频监控领域，需要实时跟踪多个移动的目标物体，以便进行行为分析和异常检测。此外，在自动驾驶领域，也需要准确跟踪其他车辆、行人和交通标志等，以实现安全驾驶和智能导航。

在比赛中，参赛者通常会被提供一个视频数据集，其中包含了多个不同的目标物体在移动的场景。他们的任务是通过算法分析视频帧，并识别和跟踪每个目标物体的运动轨迹。

参赛者需要利用计算机视觉和机器学习技术来处理视频数据集。他们可能会使用物体检测算法来寻找可能的目标物体，并利用目标追踪算法来跟踪它们的动态。此外，他们还可能需要借助特征提取和关联匹配等技术来辅助目标跟踪的准确性和稳定性。

评判一个团队的成绩通常会考虑他们的算法准确性、效率和鲁棒性。准确性是指算法可以准确地识别和跟踪目标物体的能力。效率是指算法是否能够在实时性的要求下处理视频数据。鲁棒性是指算法是否对于不同场景和环境的变化具有强适应性。

通过参加多目标跟踪比赛，研究者和开发者们可以互相切磋技艺，共同推动多目标跟踪算法的发展。这对于改善视频监控、自动驾驶、无人机等领域的应用具有重要意义。

In this paper, we have combined background information with 3D mapping of foregrounds and proposedan occlusion-free model for multiple objects tracking in a complex scenario. As a result, designing a trainedobject detector that does not overlook objects is tough. We can get noisy candidate object locations bysubtracting the background. To get an acceptable quality foreground object, we analyzed and processedeach noisy candidate region. We use the background information model to generate a graph embeddingtracker for each prospective region for localization. Objects that move in a sequential manner arelocalized and their states are updated frame by frame. A basic data relationship between backgroundreference objects and to manage size variations, object fragmentation, occlusions, and lost tracks,background subtraction is used to find targets. Because both graph embedding technique and backgroundremoval could produce errors at numerous times, object states are determined utilizing the informationfrom both. Finally, the system is tested using videos of pedestrians, moving automobiles, and otherobjects from various datasets. The benefits of adopting a robust visual tracker based on backgroundinformation in a MOT framework are demonstrated by simulation results, which demonstrate that ourtechnique is competitive even when data association is minimal.翻译成中文

在本文中，我们将背景信息与前景的3D映射相结合，提出了一种在复杂场景中无遮挡多物体跟踪的模型。因此，设计一个不会忽略物体的训练对象检测器是很困难的。我们可以通过减去背景来获取嘈杂的候选物体位置。为了得到可接受的质量前景物体，我们分析和处理了每个嘈杂的候选区域。我们使用背景信息模型为每个潜在区域生成图嵌入跟踪器以进行定位。按顺序移动的物体被定位，它们的状态逐帧更新。为了管理大小变化、物体分裂、遮挡和丢失跟踪，使用背景减法来查找目标之间的基本数据关系。由于图嵌入技术和背景去除都可能在许多时候产生错误，因此使用两者的信息来确定物体状态。最后，使用来自各种数据集的行人、移动汽车和其他物体的视频对系统进行测试。通过模拟结果展示了采用基于背景信息的强大视觉跟踪器在MOT框架中的优点，即使数据关联很少，我们的技术也是有竞争力的。

yolov8 tracking

Yolov8 is not a commonly known term. However, YOLO (You Only Look Once) is a popular object detection algorithm used in computer vision and deep learning. YOLOv4 is the latest version of this algorithm. It can detect objects in real-time with high accuracy and is widely used in applications such as self-driving cars, surveillance, and robotics.

Object tracking is the process of locating a moving object (or multiple objects) over time using a camera. This can be achieved by combining object detection with other techniques such as Kalman filtering or Deep SORT (Simple Online and Realtime Tracking algorithm). YOLOv4 can be used for object detection in tracking applications, and there are many open-source implementations of YOLOv4 with tracking capabilities available online.
