and I would like to have a black number written on white so that I can use an OCR to recognise it. How could I achieve that in Python?

推荐答案

您无需为OCR操纵图像.例如，您可以只使用 pytesser :

You don't need to manipulate the image for OCR. For example, you could just use pytesser:

from PIL import Image
from pytesser import *
im = Image.open('wjNL6.jpg')
text = image_to_string(im)
print text

输出:

0
