Today we will teach you to make an old photo repair tutorial – black and white photo coloring tips!

The body of the

** Baidu AI open platform “black and white image color”, ** this strongly recommended, 20 lines of code can handle black and white photos to color!

Step 2: Find the black and white image to color.

Step 3: You need to register as a Baidu developer, create an application, obtain API Key and Secret Key, and then obtain access_token. Input black and white image to obtain Base64 encoding of color image. Then turn the Base64 encoded string into a picture!

The attached code:

Import base64 import requests # client_id Client_secret is SK host = obtained on the official website 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id= AK&client _secret = you SK' response = requests.get(host) if response: Print (response.
