Simple tutorial: How to connect PHP to Baidu image segmentation interface?

Baidu image segmentation interface is an artificial intelligence technology that can be used in many fields such as image recognition, image processing, and image editing by segmenting different objects in the image. This tutorial will show you how to use PHP to connect to Baidu image segmentation interface to achieve image segmentation.

First of all, we need to prepare the following materials:

1. Baidu AI open platform account, used to create applications and obtain API Key and Secret Key.
2. PHP development environment, such as XAMPP, WAMP, etc., is used to run PHP code.

1. Create Baidu AI application

1. Log in to Baidu AI open platform (https://ai.baidu.com/).
2. Click "Create Application" in the "Application List".
3. Fill in the application name and select "Image Technology"->"Image Segmentation".
4. After the creation is successful, enter the application details page and obtain the API Key and Secret Key, which will be used later.

2. Install Baidu AI SDK

1. Open the command line tool and enter the root directory of the PHP environment (for example: C:
   mpphtdocs).

2. Use Composer to install Baidu AI SDK and execute the following command:

   composer require baidu-aip/php-sdk

3. Write PHP code

1. In the PHP code file, introduce Baidu AI SDK:

   require 'vendor/autoload.php';

2. Initialize the AipImageSegmentation object and set the API Key and Secret Key:

   use AipImageSegmentationAipImageSegmentation;
   
   $appId = 'your app id';
   $apiKey = 'your api key';
   $secretKey = 'your secret key';
   
   $client = new AipImageSegmentation($appId, $apiKey, $secretKey);

3. Call Baidu image segmentation interface:

   $image = file_get_contents('your image path');
   
   $response = $client->foregroundSegment($image);

   where, 'your image path' is the path of the image file to be split, which can be a local file path or URL.

4. Processing return result:

   $result = json_decode(json_encode($response), true);
   
   if ($result['error_code'] == 0) {
       $foreground = $result['foreground'];
       $background = $result['background'];
       
       // 处理分割后的前景图像和背景图像
   } else {
       echo '图像分割失败，错误码：' . $result['error_code'] . '，错误信息：' . $result['error_msg'];
   }

4. Run the test

1. Place the image file to be divided in In the same directory as the PHP code files.
2. Use a browser to access the PHP code file, and you can see the divided foreground image and background image on the web page.

Through the above steps, you can use PHP to connect to the Baidu image segmentation interface to achieve image segmentation operations. You can also further process the segmented images according to your own needs to achieve more application scenarios. Hope this tutorial helps you!
