Raspberry Pi 3 Cookbook for Python Programmers - Third Edition

How to do it...

1. Create a new Python file and import the following packages:

# Scaling (Resizing) Images - Cubic, Area, Linear Interpolations 
# Interpolation is a method of estimating values between known data points  
# Import Computer Vision package - cv2 
import cv2 
# Import Numerical Python package - numpy as np 
import numpy as np 

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

image = cv2.imread('image_3.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() 

5. Adjust the image size based on the operator's command:

# cv2.resize(image, output image size, x scale, y scale, interpolation) 

6. Adjust the image size using cubic interpolation: ...
