Details

Constants

public static final float CONFIDENCE_THRESHOLD

The minimum confidence factor of good face recognition
Constant Value: 0.4

public static final int EULER_X

The x-axis Euler angle of a face.
Constant Value: 0 (0x00000000)

public static final int EULER_Y

The y-axis Euler angle of a face.
Constant Value: 1 (0x00000001)

public static final int EULER_Z

The z-axis Euler angle of a face.
Constant Value: 2 (0x00000002)

Public Methods

public float confidence()

Returns a confidence factor between 0 and 1. This indicates how certain what has been found is actually a face. A confidence factor above 0.3 is usually good enough.

public float eyesDistance()

Returns the distance between the eyes.

public void getMidPoint(PointF point)

Sets the position of the mid-point between the eyes.

Parameters

point the PointF coordinates (float values) of the face's mid-point

public float pose(int euler)

Returns the face's pose. That is, the rotations around either the X, Y or Z axis (the positions in 3-dimensional Euclidean space).

Parameters

euler the Euler axis to retrieve an angle from (EULER_X, EULER_Y or EULER_Z)

Returns

  • the Euler angle of the of the face, for the given axis
