import cv2
import numpy as np
from matplotlib import pyplot as plt

img = cv2.imread('../../pictures/threshold.jpg')
img = img[17:159,3:147]
cv2.namedWindow('image',cv2.WINDOW_NORMAL)
cv2.imshow('image',img)

MY PROBLEM STARTS AT THIS POINT OF THE CODE (SOMETHING DOES NOT GO RIGHT WITH THE
CV2.WAITKEY(0) AND THE K==115 OR K==ORD('S') .

_**while(1):
k = cv2.waitKey(0) & 0xFF

if k == 27 :          #wait ESC key to exit
    break
elif k == 115 : #wait for 's' key to save and exit
    cv2.imwrite('../../pictures/threshold.jpg',img)
    break

cv2.destroyWindow('image')**_
