-- Detects anomalies in an image that you supply.
--
-- The response from @DetectAnomalies@ includes a boolean prediction that
-- the image contains one or more anomalies and a confidence value for the
-- prediction. If the model is an image segmentation model, the response
-- also includes segmentation information for each type of anomaly found in
-- the image.
--
-- Before calling @DetectAnomalies@, you must first start your model with
-- the StartModel operation. You are charged for the amount of time, in
-- minutes, that a model runs and for the number of anomaly detection units
-- that your model uses. If you are not using a model, use the StopModel
-- operation to stop your model.
--
-- For more information, see /Detecting anomalies in an image/ in the
-- Amazon Lookout for Vision developer guide.
--
-- This operation requires permissions to perform the
-- @lookoutvision:DetectAnomalies@ operation.
