// <br /> Note persistedFaceId is different from faceId generated by [Face -

// * Higher face image quality means better recognition precision. Please consider high-quality faces: frontal, clear,
// and face size is 200x200 pixels (100 pixels between eyes) or bigger.
// * Each person entry can hold up to 248 faces.
// * JPEG, PNG, GIF (the first frame), and BMP format are supported. The allowed image file size is from 1KB to 6MB.
// * "targetFace" rectangle should contain one face. Zero or multiple faces will be regarded as an error. If the
// provided "targetFace" rectangle is not returned from [Face -
// Detect](https://docs.microsoft.com/rest/api/cognitiveservices/face/face/detectwithurl), there’s no guarantee to
// detect and add the face successfully.
// * Out of detectable face size (36x36 - 4096x4096 pixels), large head-pose, or large occlusions will cause failures.
// * Adding/deleting faces to/from a same person will be processed sequentially. Adding/deleting faces to/from
// different persons are processed in parallel.
// * The minimum detectable face size is 36x36 pixels in an image no larger than 1920x1080 pixels. Images with
// dimensions higher than 1920x1080 pixels will need a proportionally larger minimum face size.
// * Different 'detectionModel' values can be provided. To use and compare different detection models, please refer to
// [How to specify a detection
// model](https://docs.microsoft.com/azure/cognitive-services/face/face-api-how-to-topics/specify-detection-model)
// | Model | Recommended use-case(s) |
// | ---------- | -------- |
// | 'detection_01': | The default detection model for [LargePersonGroup Person - Add

// | 'detection_02': | Detection model released in 2019 May with improved accuracy especially on small, side and blurry
// faces. |
// Parameters:
// largePersonGroupID - id referencing a particular large person group.
// personID - id referencing a particular person.
// imageParameter - an image stream.
// userData - user-specified data about the face for any purpose. The maximum length is 1KB.
// targetFace - a face rectangle to specify the target face to be added to a person in the format of
// "targetFace=left,top,width,height". E.g. "targetFace=10,10,100,100". If there is more than one face in the
// image, targetFace is required to specify which face to add. No targetFace means there is only one face
// detected in the entire image.
// detectionModel - name of detection model. Detection model is used to detect faces in the submitted image. A
// detection model name can be provided when performing Face - Detect or (Large)FaceList - Add Face or
// (Large)PersonGroup - Add Face. The default value is 'detection_01', if another model is needed, please
