Overview

# Chin

The landmarks of the chin in the features of a face.

Left and right are defined from the vantage of the viewer of the image, without considering mirror projections typical of photos. So ‘face.features.eyes.left` typically is the person’s right eye.

See Google::Cloud::Vision::Annotation::Face::Features and Google::Cloud::Vision::Annotation::Face.

Examples:

require "google/cloud/vision"

vision = Google::Cloud::Vision.new

image = vision.image "path/to/face.jpg"
face = image.face

chin = face.features.chin

chin.center
#=> #<Landmark (x: 233.21977, y: 189.47475, z: 19.487228)>
