## Overview

This is a local real-time object detection and tracking application. Its principal workflow reads frames from a webcam, video, or image; runs YOLO detection; optionally associates detections across frames; and displays or saves annotated results. The main processing and tracking paths are excerpted. The README documents additional controls and demo capabilities; configuration is present as a standalone module, but the available import index does not show it wired into the runtime.

Main entry points: [`object_detection_tracking.py`](https://github.com/naveen2002-ncg/sourcehubit-object-detection-and-tracking/blob/main/object_detection_tracking.py) (Frame processing), [`tracker.py`](https://github.com/naveen2002-ncg/sourcehubit-object-detection-and-tracking/blob/main/tracker.py) (Object tracker), [`demo.py`](https://github.com/naveen2002-ncg/sourcehubit-object-detection-and-tracking/blob/main/demo.py) (Interactive demos), [`utils.py`](https://github.com/naveen2002-ncg/sourcehubit-object-detection-and-tracking/blob/main/utils.py) (IoU calculation)
