Class

VNFaceLandmarks2D

A collection of all facial features detected in a face observation, with 2D geometry information for each.

Declaration

class VNFaceLandmarks2D : VNFaceLandmarks

Overview

This class represents the set of all detectable 2D face landmarks and regions, exposed as properties. The coordinates of the face landmarks are normalized to the dimensions of the face observation’s boundingBox, with the origin at the bounding box’s lower-left corner. Use the VNImagePointForFaceLandmarkPoint(_:_:_:_:) function to convert normalized face landmark points into absolute points within the image’s coordinate system.

Topics

Face Landmark Points

var allPoints: VNFaceLandmarkRegion2D?

var faceContour: VNFaceLandmarkRegion2D?

The region containing points that trace the face contour from the left cheek, over the chin, to the right cheek.

var leftEye: VNFaceLandmarkRegion2D?

The region containing points that outline the left eye.

var rightEye: VNFaceLandmarkRegion2D?

The region containing points that outline the right eye.

var leftEyebrow: VNFaceLandmarkRegion2D?

The region containing points that trace the left eyebrow.

var rightEyebrow: VNFaceLandmarkRegion2D?

The region containing points that trace the right eyebrow.

var nose: VNFaceLandmarkRegion2D?

The region containing points that outline the nose.

var noseCrest: VNFaceLandmarkRegion2D?

The region containing points that trace the center crest of the nose.

var medianLine: VNFaceLandmarkRegion2D?
