Properties
-
address
→ Pointer<
T> -
Available on T, provided by the StructAddress extension
The memory address of the underlying data.no setter - base_options ↔ MpBaseOptions
-
Base options for configuring MediaPipe Tasks, such as specifying the model
file with metadata, accelerator options, op resolver, etc.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- min_face_detection_confidence ↔ double
-
The minimum confidence score for the face detection to be considered
successful.
getter/setter pair
- min_face_presence_confidence ↔ double
-
The minimum confidence score of face presence score in the face landmark
detection.
getter/setter pair
- min_tracking_confidence ↔ double
-
The minimum confidence score for the face tracking to be considered
successful.
getter/setter pair
- num_faces ↔ int
-
The maximum number of faces can be detected by the FaceLandmarker.
getter/setter pair
- output_face_blendshapes ↔ bool
-
Whether FaceLandmarker outputs face blendshapes classification. Face
blendshapes are used for rendering the 3D face model.
getter/setter pair
- output_facial_transformation_matrixes ↔ bool
-
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.
getter/setter pair
-
result_callback
↔ Pointer<
NativeFunction< Void Function(UnsignedInt status, Pointer< >MpFaceLandmarkerResult> result, MpImagePtr image, Int64 timestamp_ms)> -
The user-defined result callback for processing live stream data.
The result callback should only be specified when the running mode is set
to MP_RUNNING_MODE_LIVE_STREAM. Arguments of the callback
function include: the pointer to recognition result, the image that result
was obtained on, the timestamp relevant to recognition results and pointer
to error message in case of any failure. The validity of the passed
arguments is true for the lifetime of the callback function.
getter/setter pair
- running_mode ↔ MpRunningMode
-
getter/setter pair
- running_modeAsInt ↔ int
-
The running mode of the task. Default to the image mode.
FaceLandmarker has three running modes:
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
