When I use Pytesseract to recognise the text in this image, Pytesseract returns 7A51k but the text in this image is 7,451k .
How can I fix this problem with code instead of providing a clearer source image?
my code
import pytesseract as pytesseract
from PIL import Image
pytesseract.pytesseract.tesseract_cmd = 'D:\\App\\Tesseract-OCR\\tesseract'
img = Image.open("captured\\amount.png")
string = pytesseract.image_to_string(image=img, config="--psm 10")
print(string)
I have a two-step solution
When you read the threshold image:
7,451k
Code:
import cv2
from pytesseract import image_to_string
img = cv2.imread("4ARXO.png")
(h, w) = img.shape[:2]
img = cv2.resize(img, (w*3, h*3))
gry = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
thr = cv2.threshold(gry, 0, 255, cv2.THRESH_BINARY_INV + cv2.THRESH_OTSU)[1]
txt = image_to_string(thr)
print(txt)
There is no problem if the image is blurry after resizing, you can threshold it, and invert it as AlexAlex has proposed:
output: 7,451k
import numpy as np
import pytesseract
import cv2
# Read Image
gray = cv2.imread('2.png', 0)
# Resize
gray = cv2.resize(gray, (600,200))
# Inverting
gray = 255 - gray
emp = np.full_like(gray, 255)
emp -= gray
# Thresholding
emp[emp==0] = 255
emp[emp<100] = 0
text = pytesseract.image_to_string(emp, config='outputbase digits')
print(text)
