#hellow everyone today i am going to show you #how to create a black image in opencv #first import opencv and numpy import cv2 import numpy as np #creating black image #width of the image width = 700 #height of the image height = 600 Black_image = np.zeros( (width , height) , dtype =np.uint8) #displaying image untill press ESC button while True : cv2.imshow( 'window' , Black_image) if cv2.waitKey( 1 ) == 27 : break cv2.destroyAllWindows()
