Loading, displaying, and saving images

This section presents how to work on images by means of OpenCV-Python. Furthermore, we discuss how to load, display, and save images.

How to do it...

1. Import the Computer Vision package - cv2:

import cv2 

2. Read the image using the built-in imread function:

image = cv2.imread('image_1.jpg')

3. Display the original image using the built-in imshow function:

cv2.imshow("Original", image) 

4. Wait until any key is pressed:

cv2.waitKey(0) 

5. Save the image using the built-in imwrite function:

cv2.imwrite("Saved Image.jpg", image) 

6. The command used to execute the Python program Load_Display_Save.py is shown here:

7. The result obtained after executing Load_Display_Save.py is shown here:
