=head1 NAME

Paws::Rekognition - Perl Interface to AWS Amazon Rekognition

=head1 SYNOPSIS

  use Paws;

  my $obj = Paws->service('Rekognition');
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => 'Val1'  }, { Att1 => 'Val2' } ],
  );

=head1 DESCRIPTION

This is the Amazon Rekognition API reference.

For the AWS API documentation, see L<https://docs.aws.amazon.com/goto/WebAPI/rekognition-2016-06-27>


=head1 METHODS

=head2 CompareFaces

=over

=item SourceImage => L<Paws::Rekognition::Image>

=item TargetImage => L<Paws::Rekognition::Image>

=item [QualityFilter => Str]

=item [SimilarityThreshold => Num]


=back

Each argument is described in detail in: L<Paws::Rekognition::CompareFaces>

Returns: a L<Paws::Rekognition::CompareFacesResponse> instance

Compares a face in the I<source> input image with each of the 100
largest faces detected in the I<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 C<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, role, 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 C<SimilarityThreshold> parameter.

C<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 C<QualityFilter> input parameter allows you to filter out detected
faces that donE<rsquo>t meet a required quality bar. The quality bar is
based on a variety of common use cases. Use C<QualityFilter> to set the
quality bar by specifying C<LOW>, C<MEDIUM>, or C<HIGH>. If you do not
want to filter detected faces, specify C<NONE>. The default value is
C<NONE>.

If the image doesn't contain Exif metadata, C<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,
C<CompareFaces> returns an C<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 requires permissions to perform the
C<rekognition:CompareFaces> action.


=head2 CreateCollection

=over

=item CollectionId => Str

=item [Tags => L<Paws::Rekognition::TagMap>]


=back

Each argument is described in detail in: L<Paws::Rekognition::CreateCollection>

Returns: a L<Paws::Rekognition::CreateCollectionResponse> instance

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 C<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
C<rekognition:CreateCollection> action. If you want to tag your
collection, you also require permission to perform the
C<rekognition:TagResource> operation.


=head2 CreateProject

=over

=item ProjectName => Str


=back

Each argument is described in detail in: L<Paws::Rekognition::CreateProject>

Returns: a L<Paws::Rekognition::CreateProjectResponse> instance

Creates a new Amazon Rekognition Custom Labels project. A project is a
logical grouping of resources (images, Labels, models) and operations
(training, evaluation and detection).

This operation requires permissions to perform the
C<rekognition:CreateProject> action.


=head2 CreateProjectVersion

=over

=item OutputConfig => L<Paws::Rekognition::OutputConfig>

=item ProjectArn => Str

=item TestingData => L<Paws::Rekognition::TestingData>

=item TrainingData => L<Paws::Rekognition::TrainingData>

=item VersionName => Str

=item [KmsKeyId => Str]

=item [Tags => L<Paws::Rekognition::TagMap>]


=back

Each argument is described in detail in: L<Paws::Rekognition::CreateProjectVersion>

Returns: a L<Paws::Rekognition::CreateProjectVersionResponse> instance

Creates a new version of a model and begins training. Models are
managed as part of an Amazon Rekognition Custom Labels project. You can
specify one training dataset and one testing dataset. The response from
C<CreateProjectVersion> is an Amazon Resource Name (ARN) for the
version of the model.

Training takes a while to complete. You can get the current status by
calling DescribeProjectVersions.

Once training has successfully completed, call DescribeProjectVersions
to get the training results and evaluate the model.

After evaluating the model, you start the model by calling
StartProjectVersion.

This operation requires permissions to perform the
C<rekognition:CreateProjectVersion> action.


=head2 CreateStreamProcessor

=over

=item Input => L<Paws::Rekognition::StreamProcessorInput>

=item Name => Str

=item Output => L<Paws::Rekognition::StreamProcessorOutput>

=item RoleArn => Str

=item Settings => L<Paws::Rekognition::StreamProcessorSettings>

=item [Tags => L<Paws::Rekognition::TagMap>]


=back

Each argument is described in detail in: L<Paws::Rekognition::CreateStreamProcessor>

Returns: a L<Paws::Rekognition::CreateStreamProcessorResponse> instance

Creates an Amazon Rekognition stream processor that you can use to
detect and recognize faces in a streaming video.

Amazon Rekognition Video is a consumer of live video from Amazon
Kinesis Video Streams. Amazon Rekognition Video sends analysis results
to Amazon Kinesis Data Streams.

You provide as input a Kinesis video stream (C<Input>) and a Kinesis
data stream (C<Output>) stream. You also specify the face recognition
criteria in C<Settings>. For example, the collection containing faces
that you want to recognize. Use C<Name> to assign an identifier for the
stream processor. You use C<Name> to manage the stream processor. For
example, you can start processing the source video by calling
StartStreamProcessor with the C<Name> field.

After you have finished analyzing a streaming video, use
StopStreamProcessor to stop processing. You can delete the stream
processor by calling DeleteStreamProcessor.

=item [MinConfidence => Num]


=back

Each argument is described in detail in: L<Paws::Rekognition::DetectCustomLabels>

Returns: a L<Paws::Rekognition::DetectCustomLabelsResponse> instance

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
C<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 (C<CustomLabel>) object in an array (C<CustomLabels>). Each
C<CustomLabel> object provides the label name (C<Name>), the level of
confidence that the image contains the object (C<Confidence>), and
object location information, if it exists, for the label on the image
(C<Geometry>).

During training model calculates a threshold value that determines if a
prediction for a label is true. By default, C<DetectCustomLabels>
doesn't return labels whose confidence value is below the model's
calculated threshold value. To filter labels that are returned, specify
a value for C<MinConfidence> that is higher than the model's calculated
threshold. You can get the model's calculated threshold from the
model's training results shown in the Amazon Rekognition Custom Labels
console. To get all labels, regardless of confidence, specify a
C<MinConfidence> value of 0.

You can also add the C<MaxResults> parameter to limit the number of
labels returned.

This is a stateless API operation. That is, the operation does not
persist any data.

This operation requires permissions to perform the
C<rekognition:DetectCustomLabels> action.


=head2 DetectFaces

=over

=item Image => L<Paws::Rekognition::Image>

=item [Attributes => ArrayRef[Str|Undef]]


=back

Each argument is described in detail in: L<Paws::Rekognition::DetectFaces>

Returns: a L<Paws::Rekognition::DetectFacesResponse> instance

Detects faces within an image that is provided as input.

C<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), presence
of beard, sunglasses, 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.

This is a stateless API operation. That is, the operation does not
persist any data.

This operation requires permissions to perform the
C<rekognition:DetectFaces> action.


=head2 DetectLabels

=over

=item Image => L<Paws::Rekognition::Image>

=item [MaxLabels => Int]

=item [MinConfidence => Num]


=back

Each argument is described in detail in: L<Paws::Rekognition::DetectLabels>

Returns: a L<Paws::Rekognition::DetectLabelsResponse> instance

Detects instances of real-world entities within an image (JPEG or PNG)
provided as input. This includes objects like flower, tree, and table;
events like wedding, graduation, and birthday party; and concepts like
landscape, evening, and nature.

For an example, see Analyzing Images Stored in an Amazon S3 Bucket in
the Amazon Rekognition Developer Guide.

C<DetectLabels> does not support the detection of activities. However,
activity detection is supported for label detection in videos. For more
information, see StartLabelDetection 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.

For each object, scene, and concept the API returns one or more labels.
Each label provides the object name, and the level of confidence that
the image contains the object. For example, suppose the input image has
a lighthouse, the sea, and a rock. The response includes all three
labels, one for each object.

C<{Name: lighthouse, Confidence: 98.4629}>

C<{Name: rock,Confidence: 79.2097}>

C<{Name: sea,Confidence: 75.061}>

In the preceding example, the operation returns one label for each of
the three objects. The operation can also return multiple labels for
the same object in the image. For example, if the input image shows a
flower (for example, a tulip), the operation might return the following
three labels.

C<{Name: flower,Confidence: 99.0562}>

C<{Name: plant,Confidence: 99.0562}>

C<{Name: tulip,Confidence: 99.0562}>

In this example, the detection algorithm more precisely identifies the
flower as a tulip.

In response, the API returns an array of labels. In addition, the
response also includes the orientation correction. Optionally, you can
specify C<MinConfidence> to control the confidence threshold for the
labels returned. The default is 55%. You can also add the C<MaxLabels>
parameter to limit the number of labels returned.

If the object detected is a person, the operation doesn't provide the
same facial details that the DetectFaces operation provides.

C<DetectLabels> returns bounding boxes for instances of common object
labels in an array of Instance objects. An C<Instance> object contains
a BoundingBox object, for the location of the label on the image. It
also includes the confidence by which the bounding box was detected.

C<DetectLabels> also returns a hierarchical taxonomy of detected
labels. For example, a detected car might be assigned the label I<car>.
The label I<car> has two parent labels: I<Vehicle> (its parent) and
I<Transportation> (its grandparent). The response returns the entire
list of ancestors for a label. Each ancestor is a unique label in the
response. In the previous example, I<Car>, I<Vehicle>, and
I<Transportation> are returned as unique labels in the response.

This is a stateless API operation. That is, the operation does not
persist any data.

This operation requires permissions to perform the
C<rekognition:DetectLabels> action.

=back

Each argument is described in detail in: L<Paws::Rekognition::DetectModerationLabels>

Returns: a L<Paws::Rekognition::DetectModerationLabelsResponse> instance

Detects unsafe content in a specified JPEG or PNG format image. Use
C<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 C<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.

Returns: a L<Paws::Rekognition::DetectProtectiveEquipmentResponse> instance

Detects Personal Protective Equipment (PPE) worn by people detected in
an image. Amazon Rekognition can detect the following types of PPE.

=over

=item *

Face cover

=item *

Hand cover

=item *

Head cover

=back

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.

C<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
C<SummarizationAttributes> input parameter. The summary provides the
following information.

=over

=item *

The persons detected as wearing all of the types of PPE that you
specify.

=item *

The persons detected as not wearing all of the types PPE that you
specify.

=item *

The persons detected where PPE adornment could not be determined.

=item Image => L<Paws::Rekognition::Image>

=item [Filters => L<Paws::Rekognition::DetectTextFilters>]


=back

Each argument is described in detail in: L<Paws::Rekognition::DetectText>

Returns: a L<Paws::Rekognition::DetectTextResponse> instance

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 C<DetectText> operation returns text in an array of TextDetection
elements, C<TextDetections>. Each C<TextDetection> element provides
information about a single word or line of text that was detected in
the image.

A word is one or more ISO basic latin script characters that are not
separated by spaces. C<DetectText> can detect up to 50 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 C<DetectText> operation returns
multiple lines.

To determine whether a C<TextDetection> element is a line of text or a
word, use the C<TextDetection> object C<Type> field.

To be detected, text must be within +/- 90 degrees orientation of the
horizontal axis.

Returns: a L<Paws::Rekognition::GetCelebrityRecognitionResponse> instance

Gets the celebrity recognition results for a Amazon Rekognition Video
analysis started by StartCelebrityRecognition.

Celebrity recognition in a video is an asynchronous operation. Analysis
is started by a call to StartCelebrityRecognition which returns a job
identifier (C<JobId>). When the celebrity recognition operation
finishes, Amazon Rekognition Video publishes a completion status to the
Amazon Simple Notification Service topic registered in the initial call
to C<StartCelebrityRecognition>. To get the results of the celebrity
recognition analysis, first check that the status value published to
the Amazon SNS topic is C<SUCCEEDED>. If so, call
C<GetCelebrityDetection> and pass the job identifier (C<JobId>) from
the initial call to C<StartCelebrityDetection>.

For more information, see Working With Stored Videos in the Amazon
Rekognition Developer Guide.

C<GetCelebrityRecognition> returns detected celebrities and the time(s)
they are detected in an array (C<Celebrities>) of CelebrityRecognition
objects. Each C<CelebrityRecognition> contains information about the
celebrity in a CelebrityDetail object and the time, C<Timestamp>, the
celebrity was detected.

C<GetCelebrityRecognition> only returns the default facial attributes
(C<BoundingBox>, C<Confidence>, C<Landmarks>, C<Pose>, and C<Quality>).
The other facial attributes listed in the C<Face> object of the
following response syntax are not returned. For more information, see
FaceDetail in the Amazon Rekognition Developer Guide.

By default, the C<Celebrities> array is sorted by time (milliseconds
from the start of the video). You can also sort the array by celebrity
by specifying the value C<ID> in the C<SortBy> input parameter.

The C<CelebrityDetail> object includes the celebrity identifer and
additional information urls. If you don't store the additional
information urls, you can get them later by calling GetCelebrityInfo
with the celebrity identifer.

No information is returned for faces not recognized as celebrities.

Use MaxResults parameter to limit the number of labels returned. If
there are more results than specified in C<MaxResults>, the value of
C<NextToken> in the operation response contains a pagination token for
getting the next set of results. To get the next page of results, call
C<GetCelebrityDetection> and populate the C<NextToken> request

analysis started by StartContentModeration.

Unsafe content analysis of a video is an asynchronous operation. You
start analysis by calling StartContentModeration which returns a job
identifier (C<JobId>). When analysis finishes, Amazon Rekognition Video
publishes a completion status to the Amazon Simple Notification Service
topic registered in the initial call to C<StartContentModeration>. To
get the results of the unsafe content analysis, first check that the
status value published to the Amazon SNS topic is C<SUCCEEDED>. If so,
call C<GetContentModeration> and pass the job identifier (C<JobId>)
from the initial call to C<StartContentModeration>.

For more information, see Working with Stored Videos in the Amazon
Rekognition Devlopers Guide.

C<GetContentModeration> returns detected unsafe content labels, and the
time they are detected, in an array, C<ModerationLabels>, of
ContentModerationDetection objects.

By default, the moderated labels are returned sorted by time, in
milliseconds from the start of the video. You can also sort them by
moderated label by specifying C<NAME> for the C<SortBy> input
parameter.

Since video analysis can return a large number of results, use the
C<MaxResults> parameter to limit the number of labels returned in a
single call to C<GetContentModeration>. If there are more results than
specified in C<MaxResults>, the value of C<NextToken> in the operation
response contains a pagination token for getting the next set of
results. To get the next page of results, call C<GetContentModeration>
and populate the C<NextToken> request parameter with the value of

Use the C<MaxResults> parameter to limit the number of segment
detections returned. If there are more results than specified in
C<MaxResults>, the value of C<NextToken> in the operation response
contains a pagination token for getting the next set of results. To get
the next page of results, call C<GetSegmentDetection> and populate the
C<NextToken> request parameter with the token value returned from the
previous call to C<GetSegmentDetection>.

Each argument is described in detail in: L<Paws::Rekognition::GetTextDetection>

Returns: a L<Paws::Rekognition::GetTextDetectionResponse> instance

Gets the text detection results of a Amazon Rekognition Video analysis
started by StartTextDetection.

Text detection with Amazon Rekognition Video is an asynchronous
operation. You start text detection by calling StartTextDetection which
returns a job identifier (C<JobId>) When the text detection operation
finishes, Amazon Rekognition publishes a completion status to the
Amazon Simple Notification Service topic registered in the initial call
to C<StartTextDetection>. To get the results of the text detection
operation, first check that the status value published to the Amazon
SNS topic is C<SUCCEEDED>. if so, call C<GetTextDetection> and pass the
job identifier (C<JobId>) from the initial call of
C<StartLabelDetection>.

C<GetTextDetection> returns an array of detected text
(C<TextDetections>) sorted by the time the text was detected, up to 50
words per frame of video.

Each element of the array includes the detected text, the precentage
confidence in the acuracy of the detected text, the time the text was
detected, bounding box information for where the text was located, and
unique identifiers for words and their lines.

Use MaxResults parameter to limit the number of text detections
returned. If there are more results than specified in C<MaxResults>,
the value of C<NextToken> in the operation response contains a
pagination token for getting the next set of results. To get the next
page of results, call C<GetTextDetection> and populate the C<NextToken>
request parameter with the token value returned from the previous call
to C<GetTextDetection>.

=back

Each argument is described in detail in: L<Paws::Rekognition::IndexFaces>

Returns: a L<Paws::Rekognition::IndexFacesResponse> instance

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, C<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 C<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 C<FaceModelVersion> in the response
from C<IndexFaces>

For more information, see Model Versioning in the Amazon Rekognition
Developer Guide.

If you provide the optional C<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
C<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 C<QualityFilter> input parameter allows you to filter out detected
faces that donE<rsquo>t meet a required quality bar. The quality bar is
based on a variety of common use cases. By default, C<IndexFaces>
chooses the quality bar that's used to filter faces. You can also
explicitly choose the quality bar. Use C<QualityFilter>, to set the
quality bar by specifying C<LOW>, C<MEDIUM>, or C<HIGH>. If you do not
want to filter detected faces, specify C<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, C<UnindexedFaces>. Faces
aren't indexed for reasons such as:

=over

=item *

The number of faces detected exceeds the value of the C<MaxFaces>
request parameter.

=item *

The face is too small compared to the image dimensions.

=item *

The face is too blurry.

=item *

The image is too dark.

=item *

The face has an extreme pose.

=item *

The face doesnE<rsquo>t have enough detail to be suitable for face
search.

=back

In response, the C<IndexFaces> operation returns an array of metadata
for all detected faces, C<FaceRecords>. This includes:

=over

=item *

The bounding box, C<BoundingBox>, of the detected face.

=item *

A confidence value, C<Confidence>, which indicates the confidence that
the bounding box contains a face.

=item *

A face ID, C<FaceId>, assigned by the service for each face that's
detected and stored.

=item *

An image ID, C<ImageId>, assigned by the service for the input image.

=back

If you request all facial attributes (by using the
C<detectionAttributes> parameter), Amazon Rekognition returns detailed
facial attributes, such as facial landmarks (for example, location of
eye and mouth) and other facial attributes. If you provide the same
image, specify the same collection, and use the same external ID in the
C<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: a L<Paws::Rekognition::RecognizeCelebritiesResponse> instance

Returns an array of celebrities recognized in the input image. For more
information, see Recognizing Celebrities in the Amazon Rekognition
Developer Guide.

C<RecognizeCelebrities> returns the 64 largest faces in the image. It
lists recognized celebrities in the C<CelebrityFaces> array and
unrecognized faces in the C<UnrecognizedFaces> array.
C<RecognizeCelebrities> doesn't return celebrities whose faces aren't
among the largest 64 faces in the image.

For each celebrity recognized, C<RecognizeCelebrities> returns a
C<Celebrity> object. The C<Celebrity> object contains the celebrity
name, ID, URL links to additional information, match confidence, and a
C<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 C<Celebrity> ID property as a unique identifier
for the celebrity. If you don't store the celebrity name or additional
information URLs returned by C<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.

Each argument is described in detail in: L<Paws::Rekognition::SearchFaces>

Returns: a L<Paws::Rekognition::SearchFacesResponse> instance

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
C<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 C<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.

This operation requires permissions to perform the
C<rekognition:SearchFaces> action.

Each argument is described in detail in: L<Paws::Rekognition::SearchFacesByImage>

Returns: a L<Paws::Rekognition::SearchFacesByImageResponse> instance

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 C<DetectFaces> operation and use the bounding
boxes in the response to make face crops, which then you can pass in to
the C<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 C<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, C<SearchFacesByImage>
returns an C<InvalidParameterException> error.

For an example, Searching for a Face Using an Image in the Amazon
Rekognition Developer Guide.

The C<QualityFilter> input parameter allows you to filter out detected
faces that donE<rsquo>t meet a required quality bar. The quality bar is
based on a variety of common use cases. Use C<QualityFilter> to set the
quality bar for filtering by specifying C<LOW>, C<MEDIUM>, or C<HIGH>.
If you do not want to filter detected faces, specify C<NONE>. The
default value is C<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.

This operation requires permissions to perform the
C<rekognition:SearchFacesByImage> action.
