Methods

alignCrop(Mat srcImg, Mat faceBox) → Mat
Aligns detected face with the source input image and crops it.
alignCropAsync(Mat srcImg, Mat faceBox) → Future<Mat>

Available on FaceRecognizerSF, provided by the FaceRecognizerSFAsync extension

dispose() → void
Releases the underlying native resources. Idempotent: calling it more than once is safe, but the object must not be used after dispose.
inherited
feature(Mat alignedImg, {bool clone = false}) → Mat
Extracts face feature from aligned image.
featureAsync(Mat alignedImg, {bool clone = false}) → Future<Mat>

Available on FaceRecognizerSF, provided by the FaceRecognizerSFAsync extension

freeNative() → void
Frees the native resources owned by this object. Subclasses implement the concrete free logic here; callers must use dispose instead.
override
match(Mat faceFeature1, Mat faceFeature2, {int disType = FR_COSINE}) → double
Calculates the distance between two face features.
matchAsync(Mat faceFeature1, Mat faceFeature2, {int disType = FaceRecognizerSF.FR_COSINE}) → Future<double>

Available on FaceRecognizerSF, provided by the FaceRecognizerSFAsync extension

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.

Constants

DIS_TYPE_FR_NORM_L2 → const int
DIS_TYPR_FR_COSINE → const int
FR_COSINE → const int
Definition of distance used for calculating the distance between two face features.
FR_NORM_L2 → const int
Definition of distance used for calculating the distance between two face features.
