Compare Two Images via PHP API

// optional parameters are base URL, API version and debug mode
$imagingConfig = new Configuration();
$imagingConfig->setClientSecret("ClientSecret");
$imagingConfig->setClientId("ClientId");
$imagingApi = new ImagingApi($imagingConfig);
// create search context or use existing search context ID if search context was created earlier
$apiResponse = $imagingApi->createImageSearch(new Requests\CreateImageSearchRequest());
$searchContextId = $apiResponse->getId();

// specify images for comparing (image ID is a path to image in storage)
$imageInStorage1 = "WorkFolder/Image1.jpg";
$imageInStorage2 = "WorkFolder/Image2.jpg";
// compare images
$response = $imagingApi->CompareImages(
    new Requests\CompareImagesRequest($searchContextId, 
    $imageInStorage1, null, $imageInStorage2));
$similarity = $response->getResults()[0]->getSimilarity();
