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"

gcloud = Google::Cloud.new
vision = gcloud.vision

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)>
