I’m trying to read text on this image using pytesseract library.

original-screenshot.png

Here is my code:

path = 'original-screenshot.png'

image = cv2.imread(path)
image = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
image = cv2.adaptiveThreshold(image, 255, cv2.ADAPTIVE_THRESH_MEAN_C,
                                cv2.THRESH_BINARY_INV, 101, -69)

cv2.imwrite('screenshot.png', image)

custom_config = r'--oem 3 --psm 7 -l eng -c tessedit_char_whitelist=abcdefghigklmnopqrstuvwxyz0123456789'
text = pytesseract.image_to_string(image, config=custom_config)

print(text)

Processed Image:

screenshot.png

Text Output:
01991f5

Expected Output:
o1991f5
