Let's see how we can load an image in OpenCV-Python. Create a file named
first_program.py and open it in your favorite code editor. Create a folder named
images in the current folder and make sure that you have an image named
input.jpg in that folder.
Once you do that, add the following lines to that Python file:
import cv2 img = cv2.imread('./images/input.jpg') cv2.imshow('Input image', img) cv2.waitKey()
If you run the preceding program, you will see an image being displayed in a new window.
Let's understand the previous piece of code, line by line. In the first line, we are importing the OpenCV library. We need this for all the functions we will be using in the code. In the second line, ...
