import cv2
from matplotlib import pyplot as plt

img = cv2.imread('lena.jpg', -1)
cv2.imshow('image', img)
# opencv reads image in BGR format
# and matploatlib reads image in RBG format. So we need to
# convert image to get the same result
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
plt.imshow(img)
# hides axis from image
plt.xticks([]), plt.yticks([])
plt.show()
