You can resize an image in Python using OpenCV by following the given steps. I highly recommend you get the “Computer Vision: Models, Learning, and Inference Book” to learn Computer Vision.
Open the Spyder IDE (integrated development environment).
Import the OpenCV library. If OpenCV is not installed in your system then first install it using This Method.
import cv2 #cv2 is used for OpenCV library
Now read the image from the location. In my case “F:\\AiHints” is the location and “top30.png” is the name of the image. Change it according to your image location and name.
image = cv2.imread("F:\\AiHints\\top30.png") #imread is use to read an image from a location
Now resize the image using this code and change the “width” and “height” according to your requirement.
image = cv2.resize(image,(600,300)) #width, height
This code will show the image and “original” is only a new name of an image that will show in a window.
cv2.imshow("original",image) #imshow command is use to show an image
waitKey() open the image for a specific time in milliseconds until you press any key. “destroyAllWindows()” will destroy all the windows that we created.
