Resize an image using OpenCV in Python

To open and resize an image using OpenCV in Python, you can use the cv2 module. Here’s a basic example:

import cv2

# Open an image file
image_path = 'path/to/your/image.jpg'
original_image = cv2.imread(image_path)

# Check if the image is loaded successfully
if original_image is not None:
    # Display the original image
    cv2.imshow('Original Image', original_image)

    # Resize the image
    width, height = 500, 300  # Set the new dimensions
    resized_image = cv2.resize(original_image, (width, height))

    # Display the resized image
    cv2.imshow('Resized Image', resized_image)

    # Save the resized image
    cv2.imwrite('path/to/save/resized_image.jpg', resized_image)
    print('Error: Unable to open the image.')
  1. Replace 'path/to/your/image.jpg' with the actual path to your image file.
  2. Adjust the width and height variables to set the desired dimensions for the resized image.
  3. The cv2.imshow function is used to display the original and resized images. The cv2.waitKey(0) waits for a key press before closing the image window.
  4. Finally, the cv2.imwrite function is used to save the resized image to a new file.

Make sure to install OpenCV first if you haven’t already:

pip install opencv-python

Adjust the code based on your specific requirements and file paths
