Exposes details and key points of the mouth of a detected Face
object.
Key points are returned in the detected face's local coordinate system. Use Face.cameraTransform.applyToPoint()
to convert the point to the camera's coordinate system.
Property | Description |
---|---|
| (get) center: PointSignal The location of the center of the mouth, as a PointSignal . |
| (get) leftCorner: PointSignal The location of the left corner of the mouth, as a PointSignal . |
| (get) lowerLipCenter: PointSignal The location of the center of the lower lip, as a PointSignal . |
| (get) lowerLipCurvature: ScalarSignal The curvature of the lower lip relative to the lip center, as a ScalarSignal .A value of 0 represents no curvature on the lower lip. A mouth angled higher than the lip center results in a positive curvature value, while a mouth angled lower than the lip center results in a negative curvature value. |
| (get) openness: ScalarSignal The openness of the mouth, as a ScalarSignal .The higher the value returned, the more wide open the detected mouth is. The minimum value is 0 , which indicates a closed mouth. |
| (get) rightCorner: PointSignal The location of the right corner of the mouth, as a PointSignal . |
| (get) upperLipCenter: PointSignal The location of the center of the upper lip, as a PointSignal . |
| (get) upperLipCurvature: ScalarSignal The curvature of the upper lip relative to the lip center, as a ScalarSignal .A value of 0 represents no curvature on the upper lip. A mouth angled higher than the lip center results in a positive curvature value, while a mouth angled lower than the lip center results in a negative curvature value. |
