Hi, I'm trying to threshold an image for each channel, but I don't know the best method for determining the best threshold for an image, do you know any algorithms ?
import tesserocr
from PIL import Image
import pytesseract
import matplotlib.pyplot as plt
import cv2
import imutils
import numpy as np
image = cv2.imread(r'c:\ahmed\test2.png')
bin = np.all(np.array(image<131, dtype=np.uint8), axis=2)
inverted = cv2.bitwise_not( np.uint8(255*bin))
cv2.imshow("bin", inverted)
text = pytesseract.image_to_string(inverted, lang='ara')
print(text)
with open(r"c:\ahmed\file.txt", "w", encoding="utf-8") as myfile:
myfile.write(text)
cv2.waitKey(0)
