Age detection of photos in PHP

This post demonstrates how to harness deep learning to determine the age of someone in a photo. Begin with a reference to our image recognition API:

"require": {
    "cloudmersive/cloudmersive_imagerecognition_api_client": "^1.4",
}

Then all that’s needed is to call faceDetectAge with our image file.

<?php
require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
$apiInstance = new Swagger\Client\Api\FaceApi(
    
    
    new GuzzleHttp\Client(),
    $config
);
$image_file = "/path/to/file"; // \SplFileObject | Image file to perform the operation on.  Common file formats such as PNG, JPEG are supported.
try {
    $result = $apiInstance->faceDetectAge($image_file);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling FaceApi->faceDetectAge: ', $e->getMessage(), PHP_EOL;
}
?>

Here is a sample image:

And our output for this image:

{
  "Successful": true,
  "PeopleWithAge": [
    {
      "FaceLocation": {
        "LeftX": 855,
        "TopY": 348,
        "RightX": 2277,
        "BottomY": 2099
      },
      "AgeClassificationConfidence": 0.9988910555839539,
      "AgeClass": "25-32"
    }
  ],
  "PeopleIdentified": 1
}

Our return includes the age range of the subject along with a confidence rating between 0 and 1.
