Remove similar image samples

Feature description

The removal operation takes effect within 1 minute. You can remove up to 100 sample images at a time. For more information about the parameters, see the Delete sample images API documentation.

You must use the Content Moderation endpoint to call the service using the SDK. For more information about API endpoints, see Endpoints.

Prerequisites

• Java dependencies are installed. For more information, see Installation.

  Note

  You must use the Java version described in the Installation topic to install the dependencies. Otherwise, subsequent operation calls fail.

• The Extension.Uploader utility class is downloaded and imported into your project if you submit a local image or a binary image stream for image moderation.
