Associates one or more faces with an existing UserID. Takes an array of FaceIds
. Each FaceId
that are present in the FaceIds
list is associated with the provided UserID. The maximum number of total FaceIds
per UserID is 100.
The UserMatchThreshold
parameter specifies the minimum user match confidence required for the face to be associated with a UserID that has at least one FaceID
already associated. This ensures that the FaceIds
are associated with the right UserID. The value ranges from 0-100 and default value is 75.
If successful, an array of AssociatedFace
objects containing the associated FaceIds
is returned. If a given face is already associated with the given UserID
, it will be ignored and will not be returned in the response. If a given face is already associated to a different UserID
, isn't found in the collection, doesn’t meet the UserMatchThreshold
, or there are already 100 faces associated with the UserID
, it will be returned as part of an array of UnsuccessfulFaceAssociations.
The UserStatus
reflects the status of an operation which updates a UserID representation with a list of given faces. The UserStatus
can be:
ACTIVE - All associations or disassociations of FaceID(s) for a UserID are complete.
CREATED - A UserID has been created, but has no FaceID(s) associated with it.
UPDATING - A UserID is being updated and there are current associations or disassociations of FaceID(s) taking place.

Compares a face in the source input image with each of the 100 largest faces detected in the target input image.
If the source image contains multiple faces, the service detects the largest face and compares it with each face detected in the target image.
CompareFaces uses machine learning algorithms, which are probabilistic. A false negative is an incorrect prediction that a face in the target image has a low similarity confidence score when compared to the face in the source image. To reduce the probability of false negatives, we recommend that you compare the target image against multiple source images. If you plan to use CompareFaces
to make a decision that impacts an individual's rights, privacy, or access to services, we recommend that you pass the result to a human for review and further validation before taking action.
You pass the input and target images either as base64-encoded image bytes or as references to images in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes isn't supported. The image must be formatted as a PNG or JPEG file.
In response, the operation returns an array of face matches ordered by similarity score in descending order. For each face match, the response provides a bounding box of the face, facial landmarks, pose details (pitch, roll, and yaw), quality (brightness and sharpness), and confidence value (indicating the level of confidence that the bounding box contains a face). The response also provides a similarity score, which indicates how closely the faces match.
By default, only faces with a similarity score of greater than or equal to 80% are returned in the response. You can change this value by specifying the SimilarityThreshold
parameter.
CompareFaces
also returns an array of faces that don't match the source image. For each face, it returns a bounding box, confidence value, landmarks, pose details, and quality. The response also returns information about the face in the source image, including the bounding box of the face and confidence value.
The QualityFilter
input parameter allows you to filter out detected faces that don’t meet a required quality bar. The quality bar is based on a variety of common use cases. Use QualityFilter
to set the quality bar by specifying LOW
, MEDIUM
, or HIGH
. If you do not want to filter detected faces, specify NONE
. The default value is NONE
.
If the image doesn't contain Exif metadata, CompareFaces
returns orientation information for the source and target images. Use these values to display the images with the correct image orientation.
If no faces are detected in the source or target images, CompareFaces
returns an InvalidParameterException
error.
This is a stateless API operation. That is, data returned by this operation doesn't persist.
For an example, see Comparing Faces in Images in the Amazon Rekognition Developer Guide.

This operation applies only to Amazon Rekognition Custom Labels.
Copies a version of an Amazon Rekognition Custom Labels model from a source project to a destination project. The source and destination projects can be in different AWS accounts but must be in the same AWS Region. You can't copy a model to another AWS service.
To copy a model version to a different AWS account, you need to create a resource-based policy known as a project policy. You attach the project policy to the source project by calling PutProjectPolicy. The project policy gives permission to copy the model version from a trusting AWS account to a trusted account.
For more information creating and attaching a project policy, see Attaching a project policy (SDK) in the Amazon Rekognition Custom Labels Developer Guide.
If you are copying a model version to a project in the same AWS account, you don't need to create a project policy.
Copying project versions is supported only for Custom Labels models.
To copy a model, the destination project, source project, and source model version must already exist.
Copying a model version takes a while to complete. To get the current status, call DescribeProjectVersions and check the value of Status
in the ProjectVersionDescription object. The copy operation has finished when the value of Status
is COPYING_COMPLETED
.

Creates a collection in an AWS Region. You can add faces to the collection using the IndexFaces operation.
For example, you might create collections, one for each of your application users. A user can then index faces using the IndexFaces
operation and persist results in a specific collection. Then, a user can search the collection for faces in the user-specific container.
When you create a collection, it is associated with the latest version of the face model version.
Collection names are case-sensitive.
This operation requires permissions to perform the rekognition:CreateCollection
action. If you want to tag your collection, you also require permission to perform the rekognition:TagResource
operation.

Creates a new Amazon Rekognition Custom Labels dataset. You can create a dataset by using an Amazon Sagemaker format manifest file or by copying an existing Amazon Rekognition Custom Labels dataset.
To create a training dataset for a project, specify TRAIN
for the value of DatasetType
. To create the test dataset for a project, specify TEST
for the value of DatasetType
.
The response from CreateDataset
is the Amazon Resource Name (ARN) for the dataset. Creating a dataset takes a while to complete. Use DescribeDataset to check the current status. The dataset created successfully if the value of Status
is CREATE_COMPLETE
.
To check if any non-terminal errors occurred, call ListDatasetEntries and check for the presence of errors
lists in the JSON Lines.
Dataset creation fails if a terminal error occurs (Status
= CREATE_FAILED
). Currently, you can't access the terminal error information.
For more information, see Creating dataset in the Amazon Rekognition Custom Labels Developer Guide.
This operation requires permissions to perform the rekognition:CreateDataset

This API operation initiates a Face Liveness session. It returns a SessionId
, which you can use to start streaming Face Liveness video and get the results for a Face Liveness session.
You can use the OutputConfig
option in the Settings parameter to provide an Amazon S3 bucket location. The Amazon S3 bucket stores reference images and audit images. If no Amazon S3 bucket is defined, raw bytes are sent instead.
You can use AuditImagesLimit
to limit the number of audit images returned when GetFaceLivenessSessionResults
is called. This number is between 0 and 4. By default, it is set to 0. The limit is best effort and based on the duration of the selfie-video.

Creates a new version of Amazon Rekognition project (like a Custom Labels model or a custom adapter) and begins training. Models and adapters are managed as part of a Rekognition project. The response from CreateProjectVersion
is an Amazon Resource Name (ARN) for the project version.
The FeatureConfig operation argument allows you to configure specific model or adapter settings. You can provide a description to the project version by using the VersionDescription argment. Training can take a while to complete. You can get the current status by calling DescribeProjectVersions. Training completed successfully if the value of the Status
field is TRAINING_COMPLETED
. Once training has successfully completed, call DescribeProjectVersions to get the training results and evaluate the model.
This operation requires permissions to perform the rekognition:CreateProjectVersion
action.
The following applies only to projects with Amazon Rekognition Custom Labels as the chosen feature:
You can train a model in a project that doesn't have associated datasets by specifying manifest files in the TrainingData
and TestingData
fields.
If you open the console after training a model with manifest files, Amazon Rekognition Custom Labels creates the datasets for you using the most recent manifest files. You can no longer train a model version for the project by specifying manifest files.
Instead of training with a project without associated datasets, we recommend that you use the manifest files to create training and test datasets for the project.

Creates an Amazon Rekognition stream processor that you can use to detect and recognize faces or to detect labels in a streaming video.
Amazon Rekognition Video is a consumer of live video from Amazon Kinesis Video Streams. There are two different settings for stream processors in Amazon Rekognition: detecting faces and detecting labels.
If you are creating a stream processor for detecting faces, you provide as input a Kinesis video stream (Input
) and a Kinesis data stream (Output
) stream for receiving the output. You must use the FaceSearch
option in Settings
, specifying the collection that contains the faces you want to recognize. After you have finished analyzing a streaming video, use StopStreamProcessor to stop processing.
If you are creating a stream processor to detect labels, you provide as input a Kinesis video stream (Input
), Amazon S3 bucket information (Output
), and an Amazon SNS topic ARN (NotificationChannel
). You can also provide a KMS key ID to encrypt the data sent to your Amazon S3 bucket. You specify what you want to detect by using the ConnectedHome
option in settings, and selecting one of the following: PERSON
, PET
, PACKAGE
, ALL
You can also specify where in the frame you want Amazon Rekognition to monitor with RegionsOfInterest
. When you run the StartStreamProcessor operation on a label detection stream processor, you input start and stop information to determine the length of the processing time.
Use Name
to assign an identifier for the stream processor. You use Name
to manage the stream processor. For example, you can start processing the source video by calling StartStreamProcessor with the Name
field.
This operation requires permissions to perform the rekognition:CreateStreamProcessor
action. If you want to tag your stream processor, you also require permission to perform the rekognition:TagResource
operation.

This operation applies only to Amazon Rekognition Custom Labels.
Detects custom labels in a supplied image by using an Amazon Rekognition Custom Labels model.
You specify which version of a model version to use by using the ProjectVersionArn
input parameter.
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
For each object that the model version detects on an image, the API returns a (CustomLabel
) object in an array (CustomLabels
). Each CustomLabel
object provides the label name (Name
), the level of confidence that the image contains the object (Confidence
), and object location information, if it exists, for the label on the image (Geometry
). Note that for the DetectCustomLabelsLabels
operation, Polygons
are not returned in the Geometry
section of the response.
To filter labels that are returned, specify a value for MinConfidence
. DetectCustomLabelsLabels
only returns labels with a confidence that's higher than the specified value. The value of MinConfidence
maps to the assumed threshold values created during training. For more information, see Assumed threshold in the Amazon Rekognition Custom Labels Developer Guide. Amazon Rekognition Custom Labels metrics expresses an assumed threshold as a floating point value between 0-1. The range of MinConfidence
normalizes the threshold value to a percentage value (0-100). Confidence responses from DetectCustomLabels
are also returned as a percentage. You can use MinConfidence
to change the precision and recall or your model. For more information, see Analyzing an image in the Amazon Rekognition Custom Labels Developer Guide.
If you don't specify a value for MinConfidence
, DetectCustomLabels
returns labels based on the assumed threshold of each label.
This is a stateless API operation. That is, the operation does not persist any data.
This operation requires permissions to perform the rekognition:DetectCustomLabels
action.

Detects faces within an image that is provided as input.
DetectFaces
detects the 100 largest faces in the image. For each face detected, the operation returns face details. These details include a bounding box of the face, a confidence value (that the bounding box contains a face), and a fixed set of attributes such as facial landmarks (for example, coordinates of eye and mouth), pose, presence of facial occlusion, and so on.
The face-detection algorithm is most effective on frontal faces. For non-frontal or obscured faces, the algorithm might not detect the faces or might detect faces with lower confidence.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.

For an example, see Analyzing images stored in an Amazon S3 bucket in the Amazon Rekognition Developer Guide.
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
Optional Parameters
You can specify one or both of the GENERAL_LABELS
and IMAGE_PROPERTIES
feature types when calling the DetectLabels API. Including GENERAL_LABELS
will ensure the response includes the labels detected in the input image, while including IMAGE_PROPERTIES
will ensure the response includes information about the image quality and color.
When using GENERAL_LABELS
and/or IMAGE_PROPERTIES
you can provide filtering criteria to the Settings parameter. You can filter with sets of individual labels or with label categories. You can specify inclusive filters, exclusive filters, or a combination of inclusive and exclusive filters. For more information on filtering see Detecting Labels in an Image.
When getting labels, you can specify MinConfidence
to control the confidence threshold for the labels returned. The default is 55%. You can also add the MaxLabels
parameter to limit the number of labels returned. The default and upper limit is 1000 labels. These arguments are only valid when supplying GENERAL_LABELS as a feature type.
Response Elements
For each object, scene, and concept the API returns one or more labels. The API returns the following types of information about labels:
Name - The name of the detected label.
Confidence - The level of confidence in the label assigned to a detected object.
Parents - The ancestor labels for a detected label. DetectLabels returns a hierarchical taxonomy of detected labels. For example, a detected car might be assigned the label car. The label car has two parent labels: Vehicle (its parent) and Transportation (its grandparent). The response includes the all ancestors for a label, where every ancestor is a unique label. In the previous example, Car, Vehicle, and Transportation are returned as unique labels in the response.
Aliases - Possible Aliases for the label.
Categories - The label categories that the detected label belongs to.
BoundingBox — Bounding boxes are described for all instances of detected common object labels, returned in an array of Instance objects. An Instance object contains a BoundingBox object, describing the location of the label on the input image. It also includes the confidence for the accuracy of the detected bounding box.
The API returns the following information regarding the image, as part of the ImageProperties structure:
Quality - Information about the Sharpness, Brightness, and Contrast of the input image, scored between 0 to 100. Image quality is returned for the entire image, as well as the background and the foreground.
Dominant Color - An array of the dominant colors in the image.
Foreground - Information about the sharpness, brightness, and dominant colors of the input image’s foreground.
Background - Information about the sharpness, brightness, and dominant colors of the input image’s background.
The list of returned labels will include at least one label for every detected object, along with information about that label. In the following example, suppose the input image has a lighthouse, the sea, and a rock. The response includes all three labels, one for each object, as well as the confidence in the label:
{Name: lighthouse, Confidence: 98.4629}
{Name: rock,Confidence: 79.2097}
{Name: sea,Confidence: 75.061}
The list of labels can include multiple labels for the same object. For example, if the input image shows a flower (for example, a tulip), the operation might return the following three labels.
{Name: flower,Confidence: 99.0562}
{Name: plant,Confidence: 99.0562}
{Name: tulip,Confidence: 99.0562}
In this example, the detection algorithm more precisely identifies the flower as a tulip.
If the object detected is a person, the operation doesn't provide the same facial details that the DetectFaces operation provides.
This is a stateless API operation that doesn't return any data.
This operation requires permissions to perform the rekognition:DetectLabels
action.

Detects unsafe content in a specified JPEG or PNG format image. Use DetectModerationLabels
to moderate images depending on your requirements. For example, you might want to filter images that contain nudity, but not images containing suggestive content.
To filter images, use the labels returned by DetectModerationLabels
to determine which types of content are appropriate.
For information about moderation labels, see Detecting Unsafe Content in the Amazon Rekognition Developer Guide.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
You can specify an adapter to use when retrieving label predictions by providing a ProjectVersionArn

Detects Personal Protective Equipment (PPE) worn by people detected in an image. Amazon Rekognition can detect the following types of PPE.
Face cover
Hand cover
Head cover
You pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. The image must be either a PNG or JPG formatted file.
DetectProtectiveEquipment
detects PPE worn by up to 15 persons detected in an image.
For each person detected in the image the API returns an array of body parts (face, head, left-hand, right-hand). For each body part, an array of detected items of PPE is returned, including an indicator of whether or not the PPE covers the body part. The API returns the confidence it has in each detection (person, PPE, body part and body part coverage). It also returns a bounding box (BoundingBox) for each detected person and each detected item of PPE.
You can optionally request a summary of detected PPE items with the SummarizationAttributes
input parameter. The summary provides the following information.
The persons detected as wearing all of the types of PPE that you specify.
The persons detected as not wearing all of the types PPE that you specify.
The persons detected where PPE adornment could not be determined.
This is a stateless API operation. That is, the operation does not persist any data.
This operation requires permissions to perform the rekognition:DetectProtectiveEquipment
action.

Detects text in the input image and converts it into machine-readable text.
Pass the input image as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, you must pass it as a reference to an image in an Amazon S3 bucket. For the AWS CLI, passing image bytes is not supported. The image must be either a .png or .jpeg formatted file.
The DetectText
operation returns text in an array of TextDetection elements, TextDetections
. Each TextDetection
element provides information about a single word or line of text that was detected in the image.
A word is one or more script characters that are not separated by spaces. DetectText
can detect up to 100 words in an image.
A line is a string of equally spaced words. A line isn't necessarily a complete sentence. For example, a driver's license number is detected as a line. A line ends when there is no aligned text after it. Also, a line ends when there is a large gap between words, relative to the length of the words. This means, depending on the gap between words, Amazon Rekognition may detect multiple lines in text aligned in the same direction. Periods don't represent the end of a line. If a sentence spans multiple lines, the DetectText
operation returns multiple lines.
To determine whether a TextDetection
element is a line of text or a word, use the TextDetection
object Type
field.
To be detected, text must be within +/- 90 degrees orientation of the horizontal axis.

Gets the label detection results of a Amazon Rekognition Video analysis started by StartLabelDetection.
The label detection operation is started by a call to StartLabelDetection which returns a job identifier (JobId
). When the label detection operation finishes, Amazon Rekognition publishes a completion status to the Amazon Simple Notification Service topic registered in the initial call to StartlabelDetection
.
To get the results of the label detection operation, first check that the status value published to the Amazon SNS topic is SUCCEEDED
. If so, call GetLabelDetection and pass the job identifier (JobId
) from the initial call to StartLabelDetection
.
GetLabelDetection
returns an array of detected labels (Labels
) sorted by the time the labels were detected. You can also sort by the label name by specifying NAME
for the SortBy
input parameter. If there is no NAME
specified, the default sort is by timestamp.
You can select how results are aggregated by using the AggregateBy
input parameter. The default aggregation method is TIMESTAMPS
. You can also aggregate by SEGMENTS
, which aggregates all instances of labels detected in a given segment.
The returned Labels array may include the following attributes:
Name - The name of the detected label.
Confidence - The level of confidence in the label assigned to a detected object.
Parents - The ancestor labels for a detected label. GetLabelDetection returns a hierarchical taxonomy of detected labels. For example, a detected car might be assigned the label car. The label car has two parent labels: Vehicle (its parent) and Transportation (its grandparent). The response includes the all ancestors for a label, where every ancestor is a unique label. In the previous example, Car, Vehicle, and Transportation are returned as unique labels in the response.
Aliases - Possible Aliases for the label.
Categories - The label categories that the detected label belongs to.
BoundingBox — Bounding boxes are described for all instances of detected common object labels, returned in an array of Instance objects. An Instance object contains a BoundingBox object, describing the location of the label on the input image. It also includes the confidence for the accuracy of the detected bounding box.
Timestamp - Time, in milliseconds from the start of the video, that the label was detected. For aggregation by SEGMENTS
, the StartTimestampMillis
, EndTimestampMillis
, and DurationMillis
structures are what define a segment. Although the “Timestamp” structure is still returned with each label, its value is set to be the same as StartTimestampMillis
.
Timestamp and Bounding box information are returned for detected Instances, only if aggregation is done by TIMESTAMPS
. If aggregating by SEGMENTS
, information about detected instances isn’t returned.
The version of the label model used for the detection is also returned.
Note DominantColors
isn't returned for Instances
, although it is shown as part of the response in the sample seen below.
Use MaxResults
parameter to limit the number of labels returned. If there are more results than specified in MaxResults
, the value of NextToken
in the operation response contains a pagination token for getting the next set of results. To get the next page of results, call GetlabelDetection

Detects faces in the input image and adds them to the specified collection.
Amazon Rekognition doesn't save the actual faces that are detected. Instead, the underlying detection algorithm first detects the faces in the input image. For each face, the algorithm extracts facial features into a feature vector, and stores it in the backend database. Amazon Rekognition uses feature vectors when it performs face match and search operations using the SearchFaces and SearchFacesByImage operations.
For more information, see Adding faces to a collection in the Amazon Rekognition Developer Guide.
To get the number of faces in a collection, call DescribeCollection.
If you're using version 1.0 of the face detection model, IndexFaces
indexes the 15 largest faces in the input image. Later versions of the face detection model index the 100 largest faces in the input image.
If you're using version 4 or later of the face model, image orientation information is not returned in the OrientationCorrection
field.
To determine which version of the model you're using, call DescribeCollection and supply the collection ID. You can also get the model version from the value of FaceModelVersion
in the response from IndexFaces
For more information, see Model Versioning in the Amazon Rekognition Developer Guide.
If you provide the optional ExternalImageId
for the input image you provided, Amazon Rekognition associates this ID with all faces that it detects. When you call the ListFaces operation, the response returns the external ID. You can use this external image ID to create a client-side index to associate the faces with each image. You can then use the index to find all faces in an image.
You can specify the maximum number of faces to index with the MaxFaces
input parameter. This is useful when you want to index the largest faces in an image and don't want to index smaller faces, such as those belonging to people standing in the background.
The QualityFilter
input parameter allows you to filter out detected faces that don’t meet a required quality bar. The quality bar is based on a variety of common use cases. By default, IndexFaces
chooses the quality bar that's used to filter faces. You can also explicitly choose the quality bar. Use QualityFilter
, to set the quality bar by specifying LOW
, MEDIUM
, or HIGH
. If you do not want to filter detected faces, specify NONE
.
To use quality filtering, you need a collection associated with version 3 of the face model or higher. To get the version of the face model associated with a collection, call DescribeCollection.
Information about faces detected in an image, but not indexed, is returned in an array of UnindexedFace objects, UnindexedFaces
. Faces aren't indexed for reasons such as:
The number of faces detected exceeds the value of the MaxFaces
request parameter.
The face is too small compared to the image dimensions.
The face is too blurry.
The image is too dark.
The face has an extreme pose.
The face doesn’t have enough detail to be suitable for face search.
In response, the IndexFaces
operation returns an array of metadata for all detected faces, FaceRecords
. This includes:
The bounding box, BoundingBox
, of the detected face.
A confidence value, Confidence
, which indicates the confidence that the bounding box contains a face.
A face ID, FaceId
, assigned by the service for each face that's detected and stored.
An image ID, ImageId
, assigned by the service for the input image.
If you request ALL
or specific facial attributes (e.g., FACE_OCCLUDED
) by using the detectionAttributes parameter, Amazon Rekognition returns detailed facial attributes, such as facial landmarks (for example, location of eye and mouth), facial occlusion, and other facial attributes.
If you provide the same image, specify the same collection, and use the same external ID in the IndexFaces
operation, Amazon Rekognition doesn't save duplicate face metadata.
The input image is passed either as base64-encoded image bytes, or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes isn't supported. The image must be formatted as a PNG or JPEG file.

Returns an array of celebrities recognized in the input image. For more information, see Recognizing celebrities in the Amazon Rekognition Developer Guide.
RecognizeCelebrities
returns the 64 largest faces in the image. It lists the recognized celebrities in the CelebrityFaces
array and any unrecognized faces in the UnrecognizedFaces
array. RecognizeCelebrities
doesn't return celebrities whose faces aren't among the largest 64 faces in the image.
For each celebrity recognized, RecognizeCelebrities
returns a Celebrity
object. The Celebrity
object contains the celebrity name, ID, URL links to additional information, match confidence, and a ComparedFace
object that you can use to locate the celebrity's face on the image.
Amazon Rekognition doesn't retain information about which images a celebrity has been recognized in. Your application must store this information and use the Celebrity
ID property as a unique identifier for the celebrity. If you don't store the celebrity name or additional information URLs returned by RecognizeCelebrities
, you will need the ID to identify the celebrity in a call to the GetCelebrityInfo operation.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.

For a given input face ID, searches for matching faces in the collection the face belongs to. You get a face ID when you add a face to the collection using the IndexFaces operation. The operation compares the features of the input face with faces in the specified collection.
You can also search faces without indexing faces by using the SearchFacesByImage
operation.
The operation response returns an array of faces that match, ordered by similarity score with the highest similarity first. More specifically, it is an array of metadata for each face match that is found. Along with the metadata, the response also includes a confidence
value for each face match, indicating the confidence that the specific face matches the input face.
For an example, see Searching for a face using its face ID in the Amazon Rekognition Developer Guide.

For a given input image, first detects the largest face in the image, and then searches the specified collection for matching faces. The operation compares the features of the input face with faces in the specified collection.
To search for all faces in an input image, you might first call the IndexFaces operation, and then use the face IDs returned in subsequent calls to the SearchFaces operation.
You can also call the DetectFaces
operation and use the bounding boxes in the response to make face crops, which then you can pass in to the SearchFacesByImage
operation.
You pass the input image either as base64-encoded image bytes or as a reference to an image in an Amazon S3 bucket. If you use the AWS CLI to call Amazon Rekognition operations, passing image bytes is not supported. The image must be either a PNG or JPEG formatted file.
The response returns an array of faces that match, ordered by similarity score with the highest similarity first. More specifically, it is an array of metadata for each face match found. Along with the metadata, the response also includes a similarity
indicating how similar the face is to the input face. In the response, the operation also returns the bounding box (and a confidence level that the bounding box contains a face) of the face that Amazon Rekognition used for the input image.
If no faces are detected in the input image, SearchFacesByImage
returns an InvalidParameterException
error.
For an example, Searching for a Face Using an Image in the Amazon Rekognition Developer Guide.
The QualityFilter
input parameter allows you to filter out detected faces that don’t meet a required quality bar. The quality bar is based on a variety of common use cases. Use QualityFilter
to set the quality bar for filtering by specifying LOW
