Converting RGB to Grayscale Using the Average Method in Python

When working with images in Python, one common task is converting an RGB image into a Grayscale format. This conversion is particularly useful for various image processing applications. This guide will guide you through a simple method to achieve this using the average method, ensuring that the original RGB image and the new Grayscale image are displayed side by side.

Understanding the Average Method

In the average method for converting RGB to Grayscale, we take the average of the red, green, and blue components of each pixel. The formula is as follows:

This method is straightforward and works well for many applications where a quick transformation is needed without specific weighting for the color channels.

Preparing Your Environment

To implement the conversion, you'll need to have Python installed along with the following libraries:

numpy: For numerical operations on arrays.

opencv-python: For image processing tasks.

You can install both packages using pip if you haven’t done so already:
