The 8th AI City Challenge featured five tracks that attracted unprecedented interest from 726 teams in 47 countries and regions.
Track 1 on multi-target multi-camera (MTMC) people tracking saw significant enhancements, including an expanded dataset with over 100 million bounding boxes, 3D annotations, and camera matrices. Teams employed state-of-the-art detection and re-identification models, with a focus on online tracking methods.
Track 2 introduced dense video captioning for traffic safety, using the Woven Traffic Safety (WTS) dataset to analyze pedestrian incidents. Teams leveraged large vision-language models to generate detailed captions describing the context, behavior, and safety aspects.
Track 3 on naturalistic driving action recognition utilized the expanded SynDD2 dataset to classify 16 types of distracted driving behaviors. Participants developed specialized architectures and optimization techniques to improve detection efficiency.
Track 4 explored road object detection in fisheye cameras, with the FishEye8K and FishEye1K datasets. Teams employed ensemble models and techniques like synthetic data generation and low-light enhancement to address the challenges posed by fisheye lens distortion.
Track 5 focused on detecting motorcycle helmet violations, using a dataset from an Indian city. Top teams utilized advanced object detection models, ensemble methods, and class imbalance handling strategies to achieve state-of-the-art performance.
Overall, the 8th AI City Challenge demonstrated significant advancements in computer vision and AI, with teams pushing the boundaries of performance and showcasing innovative solutions for real-world applications in retail, warehouse, and intelligent traffic systems.
