Pytesseract OCR with handwriten images - ocr

Question

I am trying to get some text from input images. Mainly my input image is some numbers on a paper. I grayscale and then black and white the image before sending it to tesseract. I keep getting empty outputs on handwriten text. On any text image that i download to test, it works(numbers or text). Have tried it with lang='eng' or empty lang argument. Would i need to do anything extra for handwriten text?
from pytesseract import pytesseract
import cv2 as cv
import tkinter as tk
from tkinter import filedialog
def grayscale(image):
return cv.cvtColor(image, cv.COLOR_BGR2RGB)
def main():
root = tk.Tk()
root.withdraw()
image_file = tk.filedialog.askopenfilename()
img = cv.imread(image_file)
# Grayscale input image
gray_image = grayscale(img)
cv.imwrite('gray_image.jpg', gray_image)
# Binarize the grayscale image
thresh, img_bw = cv.threshold(gray_image, 120, 240, cv.THRESH_BINARY)
cv.imwrite('binary_img.jpg', img_bw)
# PyTesseract OCR
pytesseract.tesseract_cmd = "C:/Program Files/Tesseract-OCR/tesseract.exe"
image_tesseract = cv.imread("new_black.jpg")
text = pytesseract.image_to_string(image_tesseract, lang='digits')
print(text)

main()
