计算机视觉国际顶级会议 CVPR 的 AI City Challenge 挑战赛（以下简称 AICity）落下帷幕，来自旷视研究院的代表队荣获 Tracked-Vehicle Retrieval by Natural Language Descriptions 赛道冠军。AICity 由 NVIDIA 公司主办，先前已成功举办过五届，AICity 旨在利用 AI 技术来提升城市空间的运营效率。第六届 AICity 挑战...
The format of inference should be similar with the A2 dataset, which is provided by 2022 AI City Challenge. The format of A2 dataset as follows: A2 user_id_* CAMERAVIEW_user_id_*.MP4 CAMERAVIEW_user_id_*.MP4 CAMERAVIEW_user_id_*.MP4 ... video_ids.csv The checkpoints after train...
此外,我们对训练集中的090.mp4进行了可视化,可以看到第12帧(图5a)中id为42的对象预测类别是DHelmet,但在的第24帧(图5b)中,它被预测为P1NoHelmet,使用CRM策略可以将该错误预测修正为DHelmet。 所提出的方法在AI City Challenge 2023的Track5验证集上进行评估。如表3所示,我们的方法取得0.8340的分数。 5 结论 ...

(Weick et al.,2005). The messy characteristics of a crisis pose a double challenge (Paulus et al.,2022) (a) data may be unavailable, uncertain, conflicting or biased, given limited access or data collection regimes – with limited options to collect additional data because of the time ...
作者在AI City Challenge 2024 Track 2的盲测集上取得了第三名的好成绩,这表明了作者解决方案的竞争力。 2 Related Works Traffic Accident Detection with Descriptions 交通事故检测旨在识别驾驶过程中的意外交通事件,例如车辆和物体之间的碰撞以及失控等情况。这个任务早期的方法[50]涉及使用手动特征提取过程,并简单地...
The AI City Challenge was created with two goals in mind: (1) pushing the boundaries of research and development in intelligent video analysis for smarter cities use cases, and (2) assessing tasks where the level of performance is enough to cause real-world adoption. Transportation is a segmen...
