calculate the height of character from binarization image OpenCV python

Question

Hello i need to calculate the height of a character from a binarzation image ( see the image bellow):

Answer 1

You can calculate the row of pixels that have the most black pixels.

import cv2
import numpy as np

pic = cv2.imread('binarized.png')[:, 50:-50, 0]

np.max(np.sum(1 - (pic//255), axis=0))

382

Using MS Paint, I was able to confirm that the height is 382 by drawing a 382 pixel line next to it. I had to exclude your black borders though.
