Get a quanity of pixels with specific color at image. Python, opencv

Question

I have small image. enter image description here b g r, not gray.

original = cv2.imread(\'im/auto5.png\')
print(original.shape)  # 27,30,3 
print(original[1         


        

Answer 1

Image in cv2 is an iterable object. So you can just iterate through all pixels to count the pixels you are looking for.

import os
import cv2
main_dir = os.path.split(os.path.abspath(__file__))[0]
file_name = 'im/auto5.png'
color_to_seek = (254, 254, 254)

original = cv2.imread(os.path.join(main_dir, file_name))

amount = 0
for x in range(original.shape[0]):
    for y in range(original.shape[1]):
        b, g, r = original[x, y]
        if (b, g, r) == color_to_seek:
            amount += 1

print(amount)
