Create a white image using NumPy in Python
Let us see how to create a white image using NumPy and cv2. A white image has all its pixels as 255.
Method 1: Using np.full() method :
Python3
# importing the librariesimport cv2import numpy as np # creating an array using np.full # 255 is code for white colorarray_created = np.full((500, 500, 3), 255, dtype = np.uint8) # displaying the imagecv2.imshow("image", array_created) |
Output:
Method 2: By creating an array using np.zeroes() :
Python3
# importing the modulesimport numpy as npimport cv2 # creating array using np.zeroes()array = np.zeros([500, 500, 3], dtype = np.uint8) # setting RGB color values as 255,255,255array[:, :] = [255, 255, 255] # displaying the imagecv2.imshow("image", array) |
Output:
