Opencv-python-resizing Image

Tryin'to resize the image but got an error saying. TypeError: resize() missing 1 required positional argument: 'image'. line 11, in img = resize(img, width = 1280)

Solution 1:

You need to say the height and the width too. :)

resized_image = cv2.resize(image, (800, 250)) # for example

First is width (800) and the second is height (250)

EDIT Maybe your code can work (I don't know) but you have forgotten cv2. before resize but I recomend you write width and height.

Solution 2:

The function resize(image, window_height) that you defined is not a method, so it should not have the self argument.

import cv2

def resize(image, window_height = 500):
    aspect_ratio = float(image.shape[1])/float(image.shape[0])
    window_width = window_height/aspect_ratioimage= cv2.resize(image, (int(window_height),int(window_width)))
    return image

When removing self, your code runs.
