// Detects Personal Protective Equipment (PPE) worn by people detected in an
// image. Amazon Rekognition can detect the following types of PPE.
// - Face cover
// - Hand cover
// - Head cover
//
// You pass the input image as base64-encoded image bytes or as a reference to an
// image in an Amazon S3 bucket. The image must be either a PNG or JPG formatted
// file. DetectProtectiveEquipment detects PPE worn by up to 15 persons detected
// in an image. For each person detected in the image the API returns an array of
// body parts (face, head, left-hand, right-hand). For each body part, an array of
// detected items of PPE is returned, including an indicator of whether or not the
// PPE covers the body part. The API returns the confidence it has in each
// detection (person, PPE, body part and body part coverage). It also returns a
// bounding box ( BoundingBox ) for each detected person and each detected item of
// PPE. You can optionally request a summary of detected PPE items with the
// SummarizationAttributes input parameter. The summary provides the following
// information.
// - The persons detected as wearing all of the types of PPE that you specify.
// - The persons detected as not wearing all of the types PPE that you specify.
// - The persons detected where PPE adornment could not be determined.
//
// This is a stateless API operation. That is, the operation does not persist any
// data. This operation requires permissions to perform the
// rekognition:DetectProtectiveEquipment action.
