Multiple Object Tracking (MOT) is widely used in various fields, such as traffic flow monitoring and crowd density estimation. Related technologies can increase productivity by enabling fully automated object recognition and mitigating the risks associated with human error. It is particularly important in public transportation. Deep learning makes it a powerful tool for handling complex tasks. Therefore, in this project, we aim to develop deep learning-based multi-object tracking method for the application of public transportation. This project compares two algorithms, Deep Simple Online and Realtime Tracking (DeepSORT) and Strong Simple Online and Realtime Tracking (StrongSORT). DeepSORT represents an early deep learning-based object tracking model, while StrongSORT builds upon this foundation, introducing enhancements like AFLink and Gaussian Smooth Interpolation (GSI) to improve tracking accuracy further. The differences are assessed through their performance on the MOT16, MOT17 and MOT20 datasets from the MOT Challenge and the road monitoring video recorded from above by surveillance camera. The experimental results show that StrongSORT consistently outperforms DeepSORT on all test datasets. Even under conditions of high congestion, StrongSORT can still achieve reasonable accuracy for multi-object tracking tasks. The performance gap is more significant in dense tracking scenarios.
