Today I'm going to share a python randomly on an image to intercept any size of the picture method, has a good reference value, I hope to help you. Together follow the editor over to see it

As shown below:

'''
Randomized Generation of Negative Samples in Machine Learning
'''
 
import cv2
import random
 
#Read the picture
img=('')
 
#h, w is the size of the image you want to capture
h=80
w=80
 
count=1
while 1:
    # Randomize x,y. This is a pixel-by-pixel range generation.
   y = (1, 890)
  x = (1, 1480)
  # Random screenshots
   cropImg = img[(y):(y + h), (x):(x + w)]
  ('pic/' + str(count) + '.png', cropImg)
  count+=1
 
  if count==2500:
    break

Above this python randomly on an image to intercept any size of the picture is all I share with you, I hope to give you a reference, and I hope you support me more.
