Global Correlation Network: End-to-End Joint Multi-Object Detection and Tracking

Understand

Multi-object tracking (MOT) has made great progress in recent years, but there are still some problems.

• Most MOT algorithms follow tracking-by-detection framework, which separates detection and tracking into two independent parts.
• Early tracking-by-detection algorithms need to do two feature extractions for detection and tracking.
• Recently, some algorithms make the feature extraction into one network, but the tracking part still relies on data association and needs complex post-processing for life cycle management.
