"""Options for the face landmarker task.
Attributes:
base_options: Base options for the face landmarker task.
running_mode: The running mode of the task. Default to the image mode.
HandLandmarker has three running modes: 1) The image mode for detecting
face landmarks on single image inputs. 2) The video mode for detecting
face landmarks on the decoded frames of a video. 3) The live stream mode
for detecting face landmarks on the live stream of input data, such as
from camera. In this mode, the "result_callback" below must be specified
to receive the detection results asynchronously.
num_faces: The maximum number of faces that can be detected by the
FaceLandmarker.
min_face_detection_confidence: The minimum confidence score for the face
detection to be considered successful.
min_face_presence_confidence: The minimum confidence score of face presence
score in the face landmark detection.
min_tracking_confidence: The minimum confidence score for the face tracking
to be considered successful.
output_face_blendshapes: Whether FaceLandmarker outputs face blendshapes
classification. Face blendshapes are used for rendering the 3D face model.
output_facial_transformation_matrixes: Whether FaceLandmarker outputs facial
transformation_matrix. Facial transformation matrix is used to transform
the face landmarks in canonical face to the detected face, so that users
can apply face effects on the detected landmarks.
result_callback: The user-defined result callback for processing live stream
data. The result callback should only be specified when the running mode
is set to the live stream mode.
