Recognizing Celebrities

Amazon Rekognition can recognize thousands of celebrities in a wide range of categories, such as entertainment and media, sports, business, and politics.

To recognize celebrities within images and get additional information about recognized celebrities, use the RecognizeCelebrities non-storage API operation. For example, in social media or news and entertainment industries where information gathering can be time critical, you can use the RecognizeCelebrities operation to identify as many as 15 celebrities in an image and return links to celebrity web pages, if they are available. Amazon Rekognition doesn't remember which image it detected a celebrity in. Your application must store this information.

If you haven't stored the additional information for a celebrity returned by RecognizeCelebrities and you want to avoid reanalyzing an image to get it, use GetCelebrityInfo. To call GetCelebrityInfo, you need the unique identifier that Rekognition assigns to each celebrity. The identifier is returned as part of the RecognizeCelebrities response for each celebrity recognized in an image.

If you have a large collection of images to process for celebrity recognition, consider using AWS Batch to process calls to RecognizeCelebrities in batches in the background. When you add a new image to your collection, you can use an AWS Lambda function to recognize celebrities by calling RecognizeCelebrities as the image is uploaded into an S3 bucket.

Calling RecognizeCelebrities

You provide an input image to RecognizeCelebrities either as image bytes or by referencing an image stored in an S3 bucket. The image must be either a .png or .jpg formatted file. For information about input image recommendations, see Working with Images. The input image quality (brightness and sharpness) is returned by RecognizeCelebrities.

RecognizeCelebrities returns an array of recognized celebrities and an array of unrecognized faces, as shown in the following example:

The response includes the following:

  • Recognized celebritiesCelebrityFaces is an array of detected celebrities. Each Celebrity object in the array contains the celebrity name and a list of URLs pointing to related content; for example, the celebrity's IMDB link. Amazon Rekognition returns an ComparedFace object that your application can use to determine where the celebrity's face is on the image and a unique identifier for the celebrity. Use the unique identifier to retrieve celebrity information later with the GetCelebrityInfo API operation.

  • Unrecognized facesUnrecognizedFaces is an array of faces that didn't match any known celebrities. Each ComparedFace object in the array contains a bounding box (as well as other information) that you can use to locate the face in the image.
