Rekognition: Empty Result
Hey Stackers.
I'm trying to use Rekognition via the AWS PHP SDK. I do, however have a problem with it. After a long time trying to figure out what's wrong and I still haven't figured it out. I'm making a request as follows;
$returnData = new stdClass();
$this->rekognition = new RekognitionClient([
'version' => 'latest',
'region' => 'eu-west-1',
'credentials' => [
'key' => 'XXXX',
'secret' => 'XXXX'
]
]);
try {
$this->basePrint = $basePrint;
$this->newPrint = $newPrint;
$faceAnalysis = $this->rekognition->compareFaces([
'SourceImage' => [
'Bytes' => base64_decode($this->basePrint),
],
'TargetImage' => [
'Bytes' => base64_decode($this->newPrint),
],
'Attributes' => ['all']
]);
$returnData->state = "success";
$returnData->matchResult = $faceAnalysis;
} catch (RekognitionException $e){
$returnData->state = "error";
$returnData->AwsErrorCode = $e->getAwsErrorCode();
$returnData->AwsErrorMessage = $e->getAwsErrorMessage();
$returnData->OriginalPrint = $this->basePrint;
$returnData->NewPrint = $this->newPrint;
}
return $returnData;
That's all fine. No excepton is thrown. However, the result of $faceAnalysis is empty. It is null. Without any error thrown. I looked it up in the documentation, and I can't find anything that would result is this behaviour.
Am I doing something wrong or am I missing something?

You pass the input and target images as base64-encoded image bytes (or as references to images in an Amazon S3 bucket).

@jarmod That's how I had it at first. However, since my variables$this->basePrintand$this->newPrintcome from a Data URL I need to decode them first. AWS will encode them. Otherwise it will return a InvalidImageFormatException.

I'd be tempted to perform the same test with these two images using the awscli. What does it report?
