-- 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.
