Create an empty face list with user-specified faceListId, name, an optional userData and recognitionModel. Up to 64 face lists are allowed in one subscription. <br /> Face list is a list of faces, up to 1,000 faces, and used by Face - Find Similar. <br /> After creation, user should use FaceList - Add Face to import the faces. No image will be stored. Only the extracted face features are stored on server until FaceList - Delete is called. <br /> Find Similar is used for scenario like finding celebrity-like faces, similar face filtering, or as a light way face identification. But if the actual use is to identify person, please use PersonGroup / LargePersonGroup and Face - Identify. <br /> Please consider LargeFaceList when the face number is large. It can support up to 1,000,000 faces. <br />'recognitionModel' should be specified to associate with this face list. The default value for 'recognitionModel' is 'recognition_01', if the latest model needed, please explicitly specify the model you need in this parameter. New faces that are added to an existing face list will use the recognition model that's already associated with the collection. Existing face features in a face list can't be updated to features extracted by another version of recognition model. Please Refer to Specify a face recognition model.
