Webcam RGB Channel Visualization using OpenCV in Python

This Python-based computer vision project demonstrates basic image acquisition and RGB channel manipulation using OpenCV and Matplotlib. An image is captured from a webcam, converted from BGR to RGB color space, and individual RGB channels are visualized using NumPy slicing.

Features

• Webcam image capture
• BGR to RGB color space conversion
• Red, Green, and Blue channel isolation
• Multi-plot visualization using Matplotlib

Technologies Used

• Python
• OpenCV
• NumPy
• Matplotlib

How to Run

1. Clone the repository:

   git clone https://github.com/muhammadhassan24560/opencv-webcam-rgb-channel-visualization.git
   

2. Navigate to the project directory:

cd opencv-webcam-rgb-channel-visualization

4. Install dependencies:

pip install -r requirements.txt

5. Run the script:

python src/webcam_rgb_channels.py

Notes

• The script captures a single frame from the webcam.
• RGB channel slicing is performed using NumPy indexing.
• Matplotlib is used for visualization instead of OpenCV windows.

Future Improvements

• Real-time video processing
• Image filtering (blur, edge detection)
