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
