Properties

Name	Type	Description
expressionSensibility	int	Sensibility of the expression classifier.
overExposureSensibility	int	Sensibility of the over-exposure classifier, from 0 to 255.
threadCount	int	Number of threads to be used for face analysis.
underExposureSensibility	int	Sensibility of the under-exposure classifier, from 0 to 255.

Methods

Name	Description
applyAlphaMask	Applies an alpha mask to suppress the background and returns a 32-bit BGRA image.
applyMask	Applies a mask to replace the background with the specified color and returns a 24-bit BGR image.
checkColorizedImage	Verifies if an image is colorized or grayscale.
computeAge	Computes the age of a detected face.
computeAttributes	Computes the attributes of a detected face.
computeBackgroundUniformity	Computes the background uniformity behind a detected face.
computeExpression	Computes the expression of a detected face.
computeEyeGaze	Computes the eye gaze of a detected face.
computeEyeOpenness	Computes the eye openness of a detected face.
computeEyeRedness	Computes the eye redness of a detected face.
computeGeometricAttributes	Computes the geometric attributes of a detected face. This function must be used for a portrait image with only one face in it.
computeGlassesAttributes	Computes the glasses attributes of a detected face. This function must be used for a portrait image with only one face in it.
computeLandmarks	Computes 68 landmarks of a detected face.
computeNoise	Measures the image noise.
computePhotographicAttributes	Computes the photographic attributes of a detected face. This function must be used for a portrait image with only one face in it.
computePose	Computes the pose of a detected face.
computePoseWithLandmarks	Computes the pose of a detected face using the specified 68-point landmarks.
detectFaceMask	Detects the presence of a face mask on a detected face.
detectOcclusions	Detects the presence of occlusions on top of a detected face.
segmentBackground	Computes face segmentation mask for background removal.
segmentFace	Computes a segmentation map of a face.
