Display OpenCV Image in Jupyter Notebook.py

from matplotlib import pyplot as plt
import cv2

img = cv2.imread('/Users/mustafa/test.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

plt.imshow(gray)
plt.title('my picture')
plt.show()

One more example for displaying a color image. Matplot lib expects img in RGB format but OpenCV provides it in BGR.

RGB_im = cv2.cvtColor(im, cv2.COLOR_BGR2RGB)
