## Overview

This is a command-line object-tracking application: a user supplies video or camera input, model weights, a device, and a display mode; the runtime detects selected objects, assigns tracks, and displays bounding boxes and optionally path lines. The sampled script shows the runtime orchestration and visualization state. Model and tracker internals are dependencies, not present in the supplied tree, so their internal stages are not expanded.

Main entry points: [`object_tracking.py`](https://github.com/quzanh1130/object_tracking_trackline/blob/master/object_tracking.py) (CLI and Runtime), [`weight/yolov9-c-converted.pt`](https://github.com/quzanh1130/object_tracking_trackline/blob/master/weight/yolov9-c-converted.pt) (YOLO Weights), [`data_ext/classes.names`](https://github.com/quzanh1130/object_tracking_trackline/blob/master/data_ext/classes.names) (Class Names)
