Background:

Multi-Object Tracking (MOT) in crowded scenes is challenging due to noisy detections and label inconsistencies.
Existing methods struggle with object birth/death and appearance/disappearance in dynamic environments.

Purpose of the Study:

To develop an advanced framework for online MOT in crowded scenes.
To improve object association and label consistency across frames using deep reinforcement learning.

Main Methods:

Introduced Improved Space-Time Neighbor-Aware Network (STNNet), enhancing the foundational STNNet architecture.
Framed online MOT as a Markov Decision Process (MDP) to learn optimal data association policies.
Integrated deep reinforcement learning for refined decision-making in complex scenarios.

Main Results:

Improved STNNet demonstrated superior performance on benchmark datasets, including the MOT Challenge.
The framework effectively handles object birth/death and appearance/disappearance transitions.
Outperformed existing methods in demanding, crowded tracking scenarios.

Conclusions:

The Improved STNNet offers an effective solution for online MOT in crowded environments.
Deep reinforcement learning integration significantly enhances tracking accuracy and robustness.
This work advances real-time video analysis for public safety and autonomous systems.
