# Face Mapper
The Face Mapper enrichment robustly detects faces in the scene video. Detections consist of the bounding box of the face. This provides you with insight into when and where faces are visible to a subject.
This enrichment automatically maps gaze data onto faces so that you can determine when a subject has been looking at them.
Additionally, this enrichment also calculates the location of the most important facial landmarks in the image for each face: left eye, right eye, nose, left mouth corner, and right mouth corner.
The face detection algorithm used under the hood for this enrichment is RetinaFace.
