YOLOv3 Object Detection using OpenCV and Python

In this tutorial, I demonstrate how to perform real-time object detection using YOLOv3 and OpenCV in Python. The video explains how to set up and use a pre-trained YOLOv3 model to detect multiple objects in a live webcam feed.

Source code:- https://github.com/NAGULME/python-pro...
What the Code Does:
Download YOLOv3 files:

We download the YOLOv3 weights, configuration files, and COCO dataset names using curl.
Load YOLOv3 model:

The YOLOv3 pre-trained weights and configuration file are loaded using OpenCV’s cv2.dnn.readNet function.
Class names:

The COCO dataset contains 80 common object categories (e.g., person, car, dog), which we load from a file (coco.names).
Blob creation and forward pass:

Each frame of the webcam video is preprocessed into a "blob" that the YOLOv3 model can analyze. It processes the frame to predict object detections.
Non-Maximum Suppression (NMS):

NMS is applied to remove overlapping bounding boxes with lower confidence scores, ensuring the most accurate boxes are kept.
Bounding boxes and labels:

Detected objects are drawn with bounding boxes around them and labeled with the object name and confidence score.
Real-time display:

The webcam feed with detections is displayed in a real-time window, and the program exits when the 'q' key is pressed.
This is a simple but powerful demonstration of how YOLOv3 can be integrated into an OpenCV project for real-time object detection.
