Pytesseract does not recognize when it's just a letter

Question

I need to recognize only one letter

But OCR does not recognize when it's just a letter

in this case I am trying to recognize the letter H but nothing shows up

What can I do to make it work?

from PIL import Image
from pytesseract import *
import cv2
img = cv2.imread('H.png',0)
edges = cv2.Canny(img,100,200)
img_new = Image.fromarray(edges)
text = pytesseract.image_to_string(img_new, lang='eng')
print (text)

Answer 1

Try the following:

    text = pytesseract.image_to_string(img_new, lang='eng', config='--psm 10')
