FairMOT
FairMOT is a multi-object tracking framework and deep learning model designed to identify and track multiple entities across video frames. It implements a unified pipeline that integrates object detection and identity re-identification into a single-stage joint network.
The system utilizes an anchor-free detection method to predict object centers and bounding box dimensions. It maintains identity consistency across consecutive frames by generating high-dimensional embedding vectors for re-identification and employing a Kalman filter for motion state prediction.
The framework covers a broad range of computer vision capabilities, including real-time object detection and the use of the Hungarian algorithm for tracklet assignment. It also includes utilities for training models on custom image datasets and generating video visualizations with overlaid bounding boxes and persistent identifiers.
