get-celebrity-recognition¶
Description¶
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 (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 StartCelebrityRecognition . To get the results of the celebrity recognition analysis, first check that the status value published to the Amazon SNS topic is SUCCEEDED . If so, call GetCelebrityDetection and pass the job identifier (JobId ) from the initial call to StartCelebrityDetection .
For more information, see Working With Stored Videos in the Amazon Rekognition Developer Guide.
GetCelebrityRecognitionreturns detected celebrities and the time(s) they are detected in an array (Celebrities) of CelebrityRecognition objects. EachCelebrityRecognitioncontains information about the celebrity in a CelebrityDetail object and the time,Timestamp, the celebrity was detected. This CelebrityDetail object stores information about the detected celebrity’s face attributes, a face bounding box, known gender, the celebrity’s name, and a confidence estimate.
Note
GetCelebrityRecognition only returns the default facial attributes (BoundingBox , Confidence , Landmarks , Pose , and Quality ). The BoundingBox field only applies to the detected face instance. The other facial attributes listed in the Face object of the following response syntax are not returned. For more information, see FaceDetail in the Amazon Rekognition Developer Guide.
By default, the 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 ID in the SortBy input parameter.
The 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 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 GetCelebrityDetection and populate the NextToken request parameter with the token value returned from the previous call to GetCelebrityRecognition .

Synopsis¶
get-celebrity-recognition
--job-id <value>
[--max-results <value>]
[--next-token <value>]
[--sort-by <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
Options¶
--job-id (string)
Job identifier for the required celebrity recognition analysis. You can get the job identifer from a call to
StartCelebrityRecognition.
--max-results (integer)
Maximum number of results to return per paginated call. The largest value you can specify is 1000. If you specify a value greater than 1000, a maximum of 1000 results is returned. The default value is 1000.
--next-token (string)
If the previous response was incomplete (because there is more recognized celebrities to retrieve), Amazon Rekognition Video returns a pagination token in the response. You can use this pagination token to retrieve the next set of celebrities.
--sort-by (string)
Sort to use for celebrities returned in
Celebritiesfield. SpecifyIDto sort by the celebrity identifier, specifyTIMESTAMPto sort by the time the celebrity was recognized.Possible values:
ID
TIMESTAMP
--cli-input-json | --cli-input-yaml (string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.
--generate-cli-skeleton (string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
