float CONFIDENCE_THRESHOLD
The minimum confidence factor of good face recognition
Constant Value: 0.4
int EULER_X
The x-axis Euler angle of a face.
Constant Value: 0 (0x00000000)
int EULER_Y
The y-axis Euler angle of a face.
Constant Value: 1 (0x00000001)
int EULER_Z
The z-axis Euler angle of a face.
Constant Value: 2 (0x00000002)
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.

void getMidPoint (PointF point)
Sets the position of the mid-point between the eyes.
Parameters | |
---|---|
point |
PointF : the PointF coordinates (float values) of the face's mid-point |
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 |
int : the Euler axis to retrieve an angle from (EULER_X, EULER_Y or EULER_Z) |
Returns | |
---|---|
float |
the Euler angle of the of the face, for the given axis |
