Page Summary
-
This documentation details globally available constants used for face detection and analysis within ML Kit.
-
Constants are provided for outlining facial features (contours) like eyes, eyebrows, lips, and nose.
-
Additional constants define modes for face detection, classification, landmark identification, and contour detection, allowing for customization of the detection process.
-
Landmark constants pinpoint specific facial points such as the mouth corners, ears, eyes, cheeks, and nose base.
-
These constants are essential for developers utilizing ML Kit's face detection capabilities to interact with and analyze facial data.
Constants
The following constants are available globally.
