With face detection, you can automatically detect human faces in an image or video. This reports the actual position of the face inside the media with size and orientation. Once a face is identified, we can further detect other body parts in it such as nose, eyes, and mouth. The face detection API detects the following:
- Bounding box of the detected face
- Tilt angle and rotating angle of the face
- Coordinates of the nose base, bottom of the mouth, left-hand side of the mouth, and right-hand side of the mouth
- Probability that the left eye is open, the right eye is open, and the person is smiling
There are a few terms associated with the face detection feature of ML Kit.
