python实现ocr识别文字

首先安装模块PIL
pip3 install PIL
再装tesseract
apt-get install tesseract-ocr
最后装pytesseract
pip3 install pytesseract

from PIL import Image

import pytesseract

images=Image.open(‘timg.jpeg’)

print(images.size)

text=pytesseract.image_to_string(images)

print(text)

使用Image.eval(r,function)将图片黑更黑白更白

from PIL import Image,ImageFilter
import pytesseract
images=Image.open(‘isk5.jpg’)
r,b,g=images.split()
def change(pix):
if pix>200:
print(pix)
return pix2
else:
return pix0.1
im_eval=Image.eval(r,change)
im_eval.show()
