Welcome to your guide on utilizing YOLOv3 for image and video object detection using OpenCV! This powerful project implements a classifier based on pretrained YOLOv3 models for detecting various objects while providing options for real-time classification. Let’s get started!

Understanding the Project

This project uses YOLOv3, a state-of-the-art object detection algorithm that can identify multiple objects in images and videos simultaneously. Imagine you’re hosting a party, and you want to know who’s walking through your door at any given moment. YOLOv3 behaves like the vigilant party host who can instantly recognize friends, family, or unexpected guests in a sea of faces and activities!

How to Use the Project

Follow these easy steps to get started:

1. Clone the Repository:
   Open your terminal and execute the following command to clone the project repository:

   git clone https://github.com/iArunava/YOLOv3-Object-Detection-with-OpenCV.git

2. Move to the Directory:
   Navigate to the cloned directory:

   cd YOLOv3-Object-Detection-with-OpenCV

3. Inference on an Image:
   To detect objects in a local image, run the following command, replacing pathtoimage with your image’s actual path:

   python3 yolo.py --image-path=pathtoimage

4. Inference on a Video:
   To detect objects in a local video file, execute:

   python3 yolo.py --video-path=pathtovideo

5. Real-time Inference using Webcam:
   Use the following command to detect objects in real time through your webcam:

   python3 yolo.py

Note: Ensure that the weights and configuration files are located in the yolov3-coco directory. If they are in a different location, specify the path when calling yolo.py. For more information, you can access help by running:

yolo.py --help
