Synopsis

Calls the Amazon Rekognition SearchUsersByImage API operation.

Syntax

Search-REKUsersByImage
-CollectionId <String>
-S3Object_Bucket <String>
-Image_Byte <Byte[]>
-MaxUser <Int32>
-S3Object_Name <String>
-QualityFilter <QualityFilter>
-UserMatchThreshold <Single>
-S3Object_Version <String>
-Select <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>
-ClientConfig <AmazonRekognitionConfig>

Description

Searches for UserIDs using a supplied image. It first detects the largest face in the image, and then searches a specified collection for matching UserIDs. The operation returns an array of UserIDs that match the face in the supplied image, ordered by similarity score with the highest similarity first. It also returns a bounding box for the face found in the input image. Information about faces detected in the supplied image, but not used for the search, is returned in an array of UnsearchedFace objects. If no valid face is detected in the image, the response will contain an empty UserMatches list and no SearchedFace object.

Parameters

-ClientConfig <AmazonRekognitionConfig>
Amazon.PowerShell.Cmdlets.REK.AmazonRekognitionClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CollectionId <String>
The ID of an existing collection containing the UserID.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Image_Byte <Byte[]>
Blob of image bytes up to 5 MBs. Note that the maximum image size you can pass to DetectCustomLabels is 4MB. The cmdlet will automatically convert the supplied parameter of type string, string[], System.IO.FileInfo or System.IO.Stream to byte[] before supplying it to the service.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesImage_Bytes
-MaxUser <Int32>
Maximum number of UserIDs to return.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxUsers
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the CollectionId parameter. The -PassThru parameter is deprecated, use -Select '^CollectionId' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-QualityFilter <QualityFilter>
A filter that specifies a quality bar for how much filtering is done to identify faces. Filtered faces aren't searched for in the collection. The default value is NONE.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-S3Object_Bucket <String>
Name of the S3 bucket.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesImage_S3Object_Bucket
-S3Object_Name <String>
S3 object key name.

AliasesImage_S3Object_Name
-S3Object_Version <String>
If the bucket is versioning enabled, you can specify the object version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesImage_S3Object_Version
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.Rekognition.Model.SearchUsersByImageResponse). Specifying the name of a property of type Amazon.Rekognition.Model.SearchUsersByImageResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UserMatchThreshold <Single>
Specifies the minimum confidence in the UserID match to return. Default value is 80.
Required?False
