Resize the image size with Python OpenCV.

import cv2

path = 'test.jpg'
img = cv2.imread(path, 1)
img_size = img.shape
height = img_size[0]
width = img_size[1]
resize_height = int(height * 0.5)
resize_width = int(width * 0.5)
new_image = cv2.resize(img, (resize_width, resize_height))
resize_file = 'resize_' + path
cv2.imwrite(resize_file, new_image)
