由于卷积神经网络（CNN）在过去的十年中检测成功，多对象跟踪（MOT）通过检测方法的使用来控制。随着数据集和基础标记网站的发布，研究方向已转向在跟踪时在包括重新识别对象的通用场景（包括重新识别（REID））上的最佳准确性。在这项研究中，我们通过提供专用的行人数据集并专注于对性能良好的多对象跟踪器的深入分析来缩小监视的范围）现实世界应用的技术。为此，我们介绍SOMPT22数据集；一套新的，用于多人跟踪的新套装，带有带注释的简短视频，该视频从位于杆子上的静态摄像头捕获，高度为6-8米，用于城市监视。与公共MOT数据集相比，这提供了室外监视的MOT的更为集中和具体的基准。我们分析了该新数据集上检测和REID网络的使用方式，分析了将MOT跟踪器分类为单发和两阶段。我们新数据集的实验结果表明，SOTA远非高效率，而单一跟踪器是统一快速执行和准确性的良好候选者，并具有竞争性的性能。该数据集将在以下网址提供：sompt22.github.io

多目标跟踪（MOT）的典型管道是使用探测器进行对象本地化，并在重新识别（RE-ID）之后进行对象关联。该管道通过对象检测和重新ID的最近进展部分而部分地激励，并且部分地通过现有的跟踪数据集中的偏差激励，其中大多数物体倾向于具有区分外观和RE-ID模型足以建立关联。为了响应这种偏见，我们希望重新强调多目标跟踪的方法也应该在对象外观不充分辨别时起作用。为此，我们提出了一个大型数据集，用于多人跟踪，人类具有相似的外观，多样化的运动和极端关节。由于数据集包含主要组跳舞视频，我们将其命名为“DanceTrack”。我们预计DanceTrack可以提供更好的平台，以开发更多的MOT算法，这些算法依赖于视觉识别并更依赖于运动分析。在我们的数据集上，我们在数据集上基准测试了几个最先进的追踪器，并在与现有基准测试中遵守DanceTrack的显着性能下降。 DataSet，项目代码和竞争服务器播放：\ url {https://github.com/danceTrack}。

This paper presents a new large scale multi-person tracking dataset -- \texttt{PersonPath22}, which is over an order of magnitude larger than currently available high quality multi-object tracking datasets such as MOT17, HiEve, and MOT20 datasets. The lack of large scale training and test data for this task has limited the community's ability to understand the performance of their tracking systems on a wide range of scenarios and conditions such as variations in person density, actions being performed, weather, and time of day. \texttt{PersonPath22} dataset was specifically sourced to provide a wide variety of these conditions and our annotations include rich meta-data such that the performance of a tracker can be evaluated along these different dimensions. The lack of training data has also limited the ability to perform end-to-end training of tracking systems. As such, the highest performing tracking systems all rely on strong detectors trained on external image datasets. We hope that the release of this dataset will enable new lines of research that take advantage of large scale video based training data.

近年来，多个对象跟踪引起了研究人员的极大兴趣，它已成为计算机视觉中的趋势问题之一，尤其是随着自动驾驶的最新发展。 MOT是针对不同问题的关键视觉任务之一，例如拥挤的场景中的闭塞，相似的外观，小物体检测难度，ID切换等，以应对这些挑战，因为研究人员试图利用变压器的注意力机制，与田径的相互关系，与田径的相互关系，图形卷积神经网络，与暹罗网络不同帧中对象的外观相似性，他们还尝试了基于IOU匹配的CNN网络，使用LSTM的运动预测。为了将这些零散的技术在雨伞下采用，我们研究了过去三年发表的一百多篇论文，并试图提取近代研究人员更关注的技术来解决MOT的问题。我们已经征集了许多应用，可能性以及MOT如何与现实生活有关。我们的评论试图展示研究人员使用过时的技术的不同观点，并为潜在的研究人员提供了一些未来的方向。此外，我们在这篇评论中包括了流行的基准数据集和指标。

对人类对象相互作用的理解在第一人称愿景（FPV）中至关重要。遵循相机佩戴者操纵的对象的视觉跟踪算法可以提供有效的信息，以有效地建模此类相互作用。在过去的几年中，计算机视觉社区已大大提高了各种目标对象和场景的跟踪算法的性能。尽管以前有几次尝试在FPV域中利用跟踪器，但仍缺少对最先进跟踪器的性能的有条理分析。这项研究差距提出了一个问题，即应使用当前的解决方案``现成''还是应进行更多特定领域的研究。本文旨在为此类问题提供答案。我们介绍了FPV中单个对象跟踪的首次系统研究。我们的研究广泛分析了42个算法的性能，包括通用对象跟踪器和基线FPV特定跟踪器。分析是通过关注FPV设置的不同方面，引入新的绩效指标以及与FPV特定任务有关的。这项研究是通过引入Trek-150（由150个密集注释的视频序列组成的新型基准数据集）来实现的。我们的结果表明，FPV中的对象跟踪对当前的视觉跟踪器构成了新的挑战。我们强调了导致这种行为的因素，并指出了可能的研究方向。尽管遇到了困难，但我们证明了跟踪器为需要短期对象跟踪的FPV下游任务带来好处。我们预计，随着新的和FPV特定的方法学会得到研究，通用对象跟踪将在FPV中受欢迎。

Multi-animal tracking (MAT), a multi-object tracking (MOT) problem, is crucial for animal motion and behavior analysis and has many crucial applications such as biology, ecology and animal conservation. Despite its importance, MAT is largely under-explored compared to other MOT problems such as multi-human tracking due to the scarcity of dedicated benchmarks. To address this problem, we introduce AnimalTrack, a dedicated benchmark for multi-animal tracking in the wild. Specifically, AnimalTrack consists of 58 sequences from a diverse selection of 10 common animal categories. On average, each sequence comprises of 33 target objects for tracking. In order to ensure high quality, every frame in AnimalTrack is manually labeled with careful inspection and refinement. To our best knowledge, AnimalTrack is the first benchmark dedicated to multi-animal tracking. In addition, to understand how existing MOT algorithms perform on AnimalTrack and provide baselines for future comparison, we extensively evaluate 14 state-of-the-art representative trackers. The evaluation results demonstrate that, not surprisingly, most of these trackers become degenerated due to the differences between pedestrians and animals in various aspects (e.g., pose, motion, and appearance), and more efforts are desired to improve multi-animal tracking. We hope that AnimalTrack together with evaluation and analysis will foster further progress on multi-animal tracking. The dataset and evaluation as well as our analysis will be made available at https://hengfan2010.github.io/projects/AnimalTrack/.

智能城市应用程序（例如智能交通路由或事故预防）依赖计算机视觉方法来确切的车辆定位和跟踪。由于精确标记的数据缺乏，从多个摄像机中检测和跟踪3D的车辆被证明是探索挑战的。我们提出了一个庞大的合成数据集，用于多个重叠和非重叠摄像头视图中的多个车辆跟踪和分割。与现有的数据集不同，该数据集仅为2D边界框提供跟踪地面真实，我们的数据集还包含适用于相机和世界坐标中的3D边界框的完美标签，深度估计以及实例，语义和泛型细分。该数据集由17个小时的标记视频材料组成，从64个不同的一天，雨，黎明和夜幕播放的340张摄像机录制，使其成为迄今为止多目标多型多相机跟踪的最广泛数据集。我们提供用于检测，车辆重新识别以及单摄像机跟踪的基准。代码和数据公开可用。

计算机视觉在智能运输系统（ITS）和交通监视中发挥了重要作用。除了快速增长的自动化车辆和拥挤的城市外，通过实施深层神经网络的实施，可以使用视频监视基础架构进行自动和高级交通管理系统（ATM）。在这项研究中，我们为实时交通监控提供了一个实用的平台，包括3D车辆/行人检测，速度检测，轨迹估算，拥塞检测以及监视车辆和行人的相互作用，都使用单个CCTV交通摄像头。我们适应了定制的Yolov5深神经网络模型，用于车辆/行人检测和增强的排序跟踪算法。还开发了基于混合卫星的基于混合卫星的逆透视图（SG-IPM）方法，用于摄像机自动校准，从而导致准确的3D对象检测和可视化。我们还根据短期和长期的时间视频数据流开发了层次结构的交通建模解决方案，以了解脆弱道路使用者的交通流量，瓶颈和危险景点。关于现实世界情景和与最先进的比较的几项实验是使用各种交通监控数据集进行的，包括从高速公路，交叉路口和城市地区收集的MIO-TCD，UA-DETRAC和GRAM-RTM，在不同的照明和城市地区天气状况。

The problem of tracking multiple objects in a video sequence poses several challenging tasks. For tracking-bydetection, these include object re-identification, motion prediction and dealing with occlusions. We present a tracker (without bells and whistles) that accomplishes tracking without specifically targeting any of these tasks, in particular, we perform no training or optimization on tracking data. To this end, we exploit the bounding box regression of an object detector to predict the position of an object in the next frame, thereby converting a detector into a Tracktor. We demonstrate the potential of Tracktor and provide a new state-of-the-art on three multi-object tracking benchmarks by extending it with a straightforward re-identification and camera motion compensation.We then perform an analysis on the performance and failure cases of several state-of-the-art tracking methods in comparison to our Tracktor. Surprisingly, none of the dedicated tracking methods are considerably better in dealing with complex tracking scenarios, namely, small and occluded objects or missing detections. However, our approach tackles most of the easy tracking scenarios. Therefore, we motivate our approach as a new tracking paradigm and point out promising future research directions. Overall, Tracktor yields superior tracking performance than any current tracking method and our analysis exposes remaining and unsolved tracking challenges to inspire future research directions.

Datasets drive vision progress, yet existing driving datasets are impoverished in terms of visual content and supported tasks to study multitask learning for autonomous driving. Researchers are usually constrained to study a small set of problems on one dataset, while real-world computer vision applications require performing tasks of various complexities. We construct BDD100K 1 , the largest driving video dataset with 100K videos and 10 tasks to evaluate the exciting progress of image recognition algorithms on autonomous driving. The dataset possesses geographic, environmental, and weather diversity, which is useful for training models that are less likely to be surprised by new conditions. Based on this diverse dataset, we build a benchmark for heterogeneous multitask learning and study how to solve the tasks together. Our experiments show that special training strategies are needed for existing models to perform such heterogeneous tasks. BDD100K opens the door for future studies in this important venue.

The 1$^{\text{st}}$ Workshop on Maritime Computer Vision (MaCVi) 2023 focused on maritime computer vision for Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicle (USV), and organized several subchallenges in this domain: (i) UAV-based Maritime Object Detection, (ii) UAV-based Maritime Object Tracking, (iii) USV-based Maritime Obstacle Segmentation and (iv) USV-based Maritime Obstacle Detection. The subchallenges were based on the SeaDronesSee and MODS benchmarks. This report summarizes the main findings of the individual subchallenges and introduces a new benchmark, called SeaDronesSee Object Detection v2, which extends the previous benchmark by including more classes and footage. We provide statistical and qualitative analyses, and assess trends in the best-performing methodologies of over 130 submissions. The methods are summarized in the appendix. The datasets, evaluation code and the leaderboard are publicly available at https://seadronessee.cs.uni-tuebingen.de/macvi.

Tracking has traditionally been the art of following interest points through space and time. This changed with the rise of powerful deep networks. Nowadays, tracking is dominated by pipelines that perform object detection followed by temporal association, also known as tracking-by-detection. We present a simultaneous detection and tracking algorithm that is simpler, faster, and more accurate than the state of the art. Our tracker, CenterTrack, applies a detection model to a pair of images and detections from the prior frame. Given this minimal input, CenterTrack localizes objects and predicts their associations with the previous frame. That's it. CenterTrack is simple, online (no peeking into the future), and real-time. It achieves 67.8% MOTA on the MOT17 challenge at 22 FPS and 89.4% MOTA on the KITTI tracking benchmark at 15 FPS, setting a new state of the art on both datasets. CenterTrack is easily extended to monocular 3D tracking by regressing additional 3D attributes. Using monocular video input, it achieves 28.3% AMOTA@0.2 on the newly released nuScenes 3D tracking benchmark, substantially outperforming the monocular baseline on this benchmark while running at 28 FPS.

卫星摄像机可以为大型区域提供连续观察，这对于许多遥感应用很重要。然而，由于对象的外观信息不足和缺乏高质量数据集，在卫星视频中实现移动对象检测和跟踪仍然具有挑战性。在本文中，我们首先构建一个具有丰富注释的大型卫星视频数据集，用于移动对象检测和跟踪的任务。该数据集由Jilin-1卫星星座收集，并由47个高质量视频组成，对象检测有1,646,038兴趣的情况和用于对象跟踪的3,711个轨迹。然后，我们引入运动建模基线，以提高检测速率并基于累积多帧差异和鲁棒矩阵完成来减少误报。最后，我们建立了第一个用于在卫星视频中移动对象检测和跟踪的公共基准，并广泛地评估在我们数据集上几种代表方法的性能。还提供了综合实验分析和富有魅力的结论。数据集可在https://github.com/qingyonghu/viso提供。

本文旨在解决多个对象跟踪（MOT），这是计算机视觉中的一个重要问题，但由于许多实际问题，尤其是阻塞，因此仍然具有挑战性。确实，我们提出了一种新的实时深度透视图 - 了解多个对象跟踪（DP-MOT）方法，以解决MOT中的闭塞问题。首先提出了一个简单但有效的主题深度估计（SODE），以在2D场景中自动以无监督的方式自动订购检测到的受试者的深度位置。使用SODE的输出，提出了一个新的活动伪3D KALMAN滤波器，即具有动态控制变量的Kalman滤波器的简单但有效的扩展，以动态更新对象的运动。此外，在数据关联步骤中提出了一种新的高阶关联方法，以合并检测到的对象之间的一阶和二阶关系。与标准MOT基准的最新MOT方法相比，提出的方法始终达到最先进的性能。

Computer vision applications in intelligent transportation systems (ITS) and autonomous driving (AD) have gravitated towards deep neural network architectures in recent years. While performance seems to be improving on benchmark datasets, many real-world challenges are yet to be adequately considered in research. This paper conducted an extensive literature review on the applications of computer vision in ITS and AD, and discusses challenges related to data, models, and complex urban environments. The data challenges are associated with the collection and labeling of training data and its relevance to real world conditions, bias inherent in datasets, the high volume of data needed to be processed, and privacy concerns. Deep learning (DL) models are commonly too complex for real-time processing on embedded hardware, lack explainability and generalizability, and are hard to test in real-world settings. Complex urban traffic environments have irregular lighting and occlusions, and surveillance cameras can be mounted at a variety of angles, gather dirt, shake in the wind, while the traffic conditions are highly heterogeneous, with violation of rules and complex interactions in crowded scenarios. Some representative applications that suffer from these problems are traffic flow estimation, congestion detection, autonomous driving perception, vehicle interaction, and edge computing for practical deployment. The possible ways of dealing with the challenges are also explored while prioritizing practical deployment.

The research community has increasing interest in autonomous driving research, despite the resource intensity of obtaining representative real world data. Existing selfdriving datasets are limited in the scale and variation of the environments they capture, even though generalization within and between operating regions is crucial to the overall viability of the technology. In an effort to help align the research community's contributions with real-world selfdriving problems, we introduce a new large-scale, high quality, diverse dataset. Our new dataset consists of 1150 scenes that each span 20 seconds, consisting of well synchronized and calibrated high quality LiDAR and camera data captured across a range of urban and suburban geographies. It is 15x more diverse than the largest cam-era+LiDAR dataset available based on our proposed geographical coverage metric. We exhaustively annotated this data with 2D (camera image) and 3D (LiDAR) bounding boxes, with consistent identifiers across frames. Finally, we provide strong baselines for 2D as well as 3D detection and tracking tasks. We further study the effects of dataset size and generalization across geographies on 3D detection methods.

This paper explores a pragmatic approach to multiple object tracking where the main focus is to associate objects efficiently for online and realtime applications. To this end, detection quality is identified as a key factor influencing tracking performance, where changing the detector can improve tracking by up to 18.9%. Despite only using a rudimentary combination of familiar techniques such as the Kalman Filter and Hungarian algorithm for the tracking components, this approach achieves an accuracy comparable to state-of-the-art online trackers. Furthermore, due to the simplicity of our tracking method, the tracker updates at a rate of 260 Hz which is over 20x faster than other state-of-the-art trackers.
