Thank you!
Hello, I have used your code and it is very helpful for me thanks. I want to compare one image with lots of other images so please suggest me a way to done this. It is very critical part for my project. I have checked this link https://docs.aws.amazon.com/rekognition/latest/dg/faces-comparefaces.html but It cannot give PHP code. So please suggest me PHP code.
ReplyDeleteYou can use 'Collection' feature here. Create a new "collection" in AWS Rek and Insert your face into that collection using "indexFaces" then you can search faces using "Search Face by Image". That's all. if you have doubt don't hesitate to ping me.
ReplyDeleteHello.
ReplyDeleteI am using your given code. Thank you for your great work.
Issues Found as follows:
1. Line Number 29,30 & 31 are ; missing at the end of each line.
2. After updating the above code I am seeing the following output.
[
{
"Similarity": 98.67130279541016,
"Face": {
"BoundingBox": {
"Width": 0.6604781746864319,
"Height": 0.5646838545799255,
"Left": 0.11811203509569168,
"Top": 0.09955057501792908
},
"Confidence": 99.99998474121094,
My Question is How I can extract only "Similarity" value?
There is NO FaceMatches as you shown in the output.
//Calling Compare Face function
ReplyDelete$compareFaceResults = $rekognitionClient->compareFaces([
'SimilarityThreshold' => 80,
'SourceImage' => [
'Bytes' => file_get_contents($stored_face)
],
'TargetImage' => [
'Bytes' => file_get_contents($current_face)
],
]);
$FaceMatchesResult = $compareFaceResults['FaceMatches'];
$SimilarityResult = $FaceMatchesResult[0]['Similarity'];
echo json_encode($SimilarityResult);
