The second step ： find Image effects Inside Black and white image coloring .

The third step ： Register as Baidu developer , Create an , obtain API Key and Secret Key, And then you get access_token, Input black-and-white image to obtain color image Base64 code . then Base64 The encoding string can be converted into a picture .

2. Source code

import base64
import requests
  
# client_id  Obtained for the official website AK, client_secret  Obtained for the official website SK
host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id= Yours AK&client_secret= Yours SK'

f = open('test.png', 'rb')
img = base64.b64encode(f.read())
  
params = {"image":img}
access_token = response.json()['access_token']
request_url = request_url + "?access_token=" + access_token
headers = {'content-type': 'application/x-www-form-urlencoded'}
response = requests.post(request_url, data=params, headers=headers)
if response:
    print(response.json())
  
# base64 Code to picture 
img = base64.b64decode(response.json()['image'])
file = open('result.jpg', 'wb')
file.write(img)
file.close()
 Copy code 

3. The effect is as follows

These old photos have a mysterious veil , When we lift this veil , It will be a very precious treasure .
