Question

我正在使用Amazon重新认知来比较php中的面孔（AWS SDK for php Here文档。

以下代码

<?php
require 'aws.phar';

$s3 = new \Aws\Rekognition\RekognitionClient([
'version' => 'latest',
'region'  => 'us-east-1',
]);

$result = $s3->compareFaces([
    'SimilarityThreshold' => 90,
    'SourceImage' => [
          'Bytes' => file_get_contents("https://images.clarin.com/2017/10/23/BkeLV_s6W_930x525.jpg")        
    ],
    'TargetImage' => [
          'Bytes' => file_get_contents("https://pbs.twimg.com/profile_images/653558348273569792/joxg8DZD_400x400.png")
    ],
]);

?>

我不知道php。我怎样才能获得图片的信心？我尝试了一些东西，但我无法得到它。

显示如何使用Aws \ Rekognition \ RekognitionClient对象来调用比较面操作。的 PHP：

使用识别客户端

require 'vendor/aws/aws-autoloader.php'; use Aws\Rekognition\RekognitionClient;

访问AWS服务代码参数的凭据

$credentials = new Aws\Credentials\Credentials('{AWS access key ID}', '{AWS secret access key}');

获取Rekognition Access

$rekognitionClient = RekognitionClient::factory(array( 'region' => "us-east-1", 'version' => 'latest', 'credentials' => $credentials ));

调用比较面部功能

$compareFaceResults= $rekognitionClient->compareFaces([ 'SimilarityThreshold' => 80, 'SourceImage' => [ 'Bytes' => file_get_contents("SourceImage.jpg") ], 'TargetImage' => [ 'Bytes' => file_get_contents("TargetImage.jpg") ], ]);

对JSON数据的响应

$FaceMatchesResult = $compareFaceResults['FaceMatches']; $SimilarityResult = $FaceMatchesResult['Similarity'] //Here You will get similarity $sourceImageFace = $compareFaceResults['SourceImageFace'] $sourceConfidence = $sourceImageFace['Confidence'] // //Here You will get confidence of the picture

注意：AWS结果示例： -

{ "SourceImageFace": { "BoundingBox": { "Width": 0.4662500023841858, "Height": 0.6998124122619629, "Left": 0.5024999976158142, "Top": 0.09849905967712402 }, "Confidence": 99.99332427978516 }, "FaceMatches": [ { "Similarity": 93, "Face": { "BoundingBox": { "Width": 0.23999999463558197, "Height": 0.3602251410484314, "Left": 0.43937501311302185, "Top": 0.17823639512062073 }, "Confidence": 99.99273681640625, "Landmarks": [ { "Type": "eyeLeft", "X": 0.5512950420379639, "Y": 0.32593753933906555 } .................... .................... ], "Pose": { "Roll": 13.300010681152344, "Yaw": 48.84736251831055, "Pitch": -11.894044876098633 }, "Quality": { "Brightness": 45.3167610168457, "Sharpness": 99.99671173095703 } } }, "UnmatchedFaces": [] }
