📝 摘要(中文)
多目标跟踪是计算机视觉中的经典领域,尤其是行人跟踪具有极高的应用价值。现有方法主要依赖运动或外观信息进行跟踪,但在复杂场景中常面临挑战。运动信息因物体间的相互遮挡而难以更新,外观信息则因部分可见性或模糊图像而导致结果不稳。现有的多目标跟踪数据集在场景复杂性和真实场景方面存在不足。为此,本文提出了一个名为“CrowdTrack”的大型数据集,主要从第一人称视角拍摄,包含33个视频和5185条轨迹,旨在为复杂场景下的算法开发提供平台。

📄 摘要(原文)
Multi-object tracking is a classic field in computer vision. Among them, pedestrian tracking has extremely high application value and has become the most popular research category. Existing methods mainly use motion or appearance information for tracking, which is often difficult in complex scenarios. For the motion information, mutual occlusions between objects often prevent updating of the motion state; for the appearance information, non-robust results are often obtained due to reasons such as only partial visibility of the object or blurred images. Although learning how to perform tracking in these situations from the annotated data is the simplest solution, the existing MOT dataset fails to satisfy this solution. Existing methods mainly have two drawbacks: relatively simple scene composition and non-realistic scenarios. Although some of the video sequences in existing dataset do not have the above-mentioned drawbacks, the number is far from adequate for research purposes. To this end, we propose a difficult large-scale dataset for multi-pedestrian tracking, shot mainly from the first-person view and all from real-life complex scenarios. We name it ``CrowdTrack'' because there are numerous objects in most of the sequences. Our dataset consists of 33 videos, containing a total of 5,185 trajectories. Each object is annotated with a complete bounding box and a unique object ID. The dataset will provide a platform to facilitate the development of algorithms that remain effective in complex situations. We analyzed the dataset comprehensively and tested multiple SOTA models on our dataset. Besides, we analyzed the performance of the foundation models on our dataset.
