Method Details

updateKdTree

public void updateKdTree(HumanFace face,
 FaceStateServices.Mode mode)

Manages a k-d tree storing the mesh of given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateLeftBalancedKdTree

public void updateLeftBalancedKdTree(HumanFace face,
 FaceStateServices.Mode mode)

Manages a left-balanced k-d tree storing the mesh of given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateOctree

public void updateOctree(HumanFace face,
 FaceStateServices.Mode mode)

Manages an octree storing the mesh of given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateBoundingBox

public void updateBoundingBox(HumanFace face,
 FaceStateServices.Mode mode)

Manages bounding box of the given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateGlyphs

public void updateGlyphs(HumanFace face,
 FaceStateServices.Mode mode,
 PointSamplingConfig.Method method,
 int maxSamples)

Manages glyphs of the given human face.

Parameters:

face - Human face

mode - Operation to be performed

method - Sub-sampling method

maxSamples - Maximum number of glyphs

updateCurvature

public void updateCurvature(HumanFace face,
 FaceStateServices.Mode mode)

Manages curvature values of the given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateLandmarksVicinity

public void updateLandmarksVicinity(HumanFace face,
 FaceStateServices.Mode mode)

Computes vicinity of all landmarks of the given human face.

Parameters:

face - Human face

mode - Operation to be performed

updateSymmetryPlane

public void updateSymmetryPlane(HumanFace face,
 FaceStateServices.Mode mode,
 SymmetryConfig meshSymmetryConfig)

Computes symmetry plane from mesh or landmarks.

Parameters:

face - Human face

mode - Operation to be performed

meshSymmetryConfig - Configuration of the mesh symmetry calculation (when needed). If null, then the symmetry plane is computed from landmarks.

measureSymmetry

public MeshDistances measureSymmetry(HumanFace face,
 int precision)

Measures the symmetry by reflecting the mesh over the symmetry plane, (optionally) registering the reflected mesh to the original surface, and then measuring distances of the original mesh towards the reflected mesh (excluding non-overlapping areas).

Parameters:

face - Human face with symmetry plane already computed

precision - A value between 0 and 100. Zero means fast measurement when no registration is performed (only reflection of the mesh). 100 means slow but precise measurement when ICP registration is used without subsampling. The values between use ICP registration with certain level of subsampling.*

Returns:

Measured distances between the original mesh and its clone reflected over the symmetry plane and optionally registered using ICP. Non-overlapping areas are excluded from the measurement.

computeVicinity

protected void computeVicinity(HumanFace face)

updateFaceFrontalDirection

public void updateFaceFrontalDirection(HumanFace face,
 FaceStateServices.Mode mode)

Computes face frontal direction.

Parameters:

face - Human face

mode - Operation to be performed
