Face Recognition Engine Configuration Parameters

The Face Recognition analysis engine performs face recognition on faces that are detected in video. Before using this engine you must train Media Server to recognize faces, by providing images of people who you want to recognize.

This section describes the parameters that you can set in the configuration section for a Face Recognition task.

Configuration Parameter Description
Database A face database to use to recognize faces in an image. Media Server compares the detected faces to faces in this database.
FrameRate The number of frames to analyze per second of video.
Identifier A comma-separated list of identifiers that specifies the faces to match against.
Input The track that you want to analyze.
MaxRecognitionResults The maximum number of recognition results to return per face.
RecognitionThreshold The minimum confidence score required to consider a face as a match.
Type The analysis engine to use. Set this parameter to FaceRecognize.

Output Tracks

Output track Type Description Output1This column indicates whether the information contained in the track is included by default in the output created by an output task (when you don't set the Input parameter for the output task).
Result FaceRecognitionResult Contains a record for each detected face. Yes
ResultWithSource FaceRecognitionAndImage Contains the same information as the Result track, but each record also includes the best source frame. No

FaceRecognitionResult

Field name Type Description
id UUIDData A universally unique identifier to identify the face
face FaceData Information about the detected face
identity IdentityData

The identity of the person who matches the detected face. If the face was not recognized, this field is empty.

FaceRecognitionAndImage

Field name Type Description
id UUIDData A universally unique identifier to identify the face
face FaceData Information about the detected face
identity IdentityData The identity of the person who matches the detected face. If the face was not recognized, this field is empty.
