Baidu Smart Cloud Portrait Segmentation Case Teaching: back-end java realizes ID card portrait segmentation and background color change

① Go to  Baidu Smart Cloud - Intelligent Era Infrastructure  and search for "Portrait Segmentation". After real-name authentication, you can get free trial times

②Get Access_token

String accessToken = "[access_token]"

Here you need to go to another interface to get Access_token. Get the tutorial: https://ai.baidu.com/ai-doc/REFERENCE/Ck3dwjhhu

To save trouble here, I choose to use postman to get Access_token

 

 ③Fill the Access_token into the code below. Change the image file path to the path you need. The tool classes required in the code can be downloaded directly through the URL in the comment

The code below comes from the Baidu portrait segmentation development document, I made a little modification.
