Converting an Image to Grayscale Using OpenCV in Python

Are you looking to convert an image into grayscale using Python and OpenCV? If you're encountering issues while trying to achieve this, don't worry! You're not alone, and in this post, we'll guide you through this process step by step.

The Problem

In the original code provided, an image is loaded and an attempt is made to convert it to grayscale. However, the displayed output is still the original image. This common issue can be easily resolved by making a small adjustment in the code.

The Original Code

Here’s a snapshot of the code that was initially provided:

As you can see, the line responsible for displaying the image is still referencing the original color image (img) instead of the newly created grayscale image (grayscaled_img).

The Solution

Step 1: Adjust the Display Function

To fix this issue, you need to modify the line where the image is displayed. Instead of showing the original image, you should display the grayscale version. Here’s the updated line:

Run the Script: Save the corrected code to a .py file and run it. If your image path is correct and OpenCV is set up, you should see the grayscale version of the image displayed.

Conclusion

Converting an image to grayscale in OpenCV is straightforward once you know the correct method. By simply adjusting the line of code responsible for displaying the image, you can easily see the changes.
