extends VNDetectedObjectObservation

VNFaceObservation [@superclass] VNDetectedObjectObservation

VNFaceObservation is the result of a face detection request or derivatives like a face landmark request.

The properties filled in this obervation depend on the request being performed. For instance, if just a VNDetectFaceRectanglesRequest was performed the landmarks will not be populated. VNFaceObservation are also used as inputs to other request as defined by the VNFaceObservationAccepting protocol. An example would be the VNDetectFaceLandmarksRequest. This can be helpful for instance if the face rectangles in an image are not derived from a VNDetectFaceRectanglesRequest but instead come from other sources like EXIF or other face detectors. In that case the client of the API creates a VNFaceObservation with the boundingBox (in normalized coordinates) that were based on those detected faces.

Create a new VNFaceObservation with a normalized bounding box, roll and yaw.

Parameters:

requestRevision - The revision of the VNDetectFaceRectanglesRequest that provided the bounding box. If this observation is being created with data that did not originate from a Vision request, this parameter should be VNRequestRevisionUnspecified.

roll - The roll angle of the face, reported in radians. A positive angle corresponds to counterclockwise direction, range [-Pi, Pi). If no roll information is available, this parameter should be nil.

yaw - The yaw angle of the face, reported in radians. A positive angle corresponds to counterclockwise direction, range [-Pi/2, Pi/2). If no yaw information is available, this parameter should be nil.

pitch - The pitch angle of the face, reported in radians. A positive angle corresponds to nodding head down direction, range [-Pi/2, Pi/2]. If no pitch information is available, this parameter should be nil.
