Color-Detection-with-Python-and-OpenCV

Color Detection with Python and OpenCV

This repository showcases a Python script utilizing OpenCV to detect specific colors in real-time video capture.

Key Features:

• Flexible Color Selection: Supports detecting any color you choose by adjusting the script's color definitions.
• Real-time Detection: Analyzes each frame of your webcam input to highlight the chosen color in real-time.
• Bounding Box Visualization: Draws a bounding box around the detected color region for clear identification.

Prerequisites:

• Python 3: Ensure you have Python 3 installed on your system.
• OpenCV: Install OpenCV library through pip install opencv-python.
• Alternative installation methods: Install OpenCV and other library: pip install -r requirements.txt.
• util.py: This repository includes a separate util.py file containing the get_limits function responsible for calculating HSV limits of the chosen color.

Getting Started:

1. Clone the repository or download the zip file.
2. Install OpenCV if not already done.
3. Run the script main02.py.
4. Observe the webcam feed with a highlighted bounding box around the detected color.
5. Modify the yellow variable in main01.py to any desired BGR color tuple (e.g., (255, 0, 0) for red) to track different colors.

Customization:

• Adjust the lowerlimit and upperlimit values in the get_limits function for finer control over the detected color range.
• Explore using different color spaces like Lab or grayscale for specific scenarios where HSV might not be ideal.
• Implement additional functionalities like counting instances of the detected color or triggering actions based on its presence.

Contributing:

• Feel free to fork and improve the code! Pull requests with bug fixes, enhancements, or new features are welcome.
• Share your experiences and challenges to further develop the project's capabilities.

Note: This script and its color detection accuracy might be affected by lighting conditions, object textures, and camera quality. Experiment and adjust settings for optimal results in your specific environment.

I hope this README file provides a clear overview of the project and encourages you to explore and contribute to color detection with Python and OpenCV!
