Then the geometric error is computed from the set of point coordinates provided by the machine.
Firstly, with the properties of cross-ratio, the corresponding spatial point coordinates are obtained.
The extrapolated results will be valid only if the gauss point coordinates are given in their undeformed state.
Kriging characterizes the correlation between the mesh point coordinates of a face model and a set of feature parameters.
The objective and constraints are nonlinear polynomial functions of the point coordinates defining the cross-sectional shape.
Finally, the effect of uncertainty in the point coordinates is considered by means of a bootstrap analysis.
The motion trail is solved according to the feature point coordinates on the reference plane in different frames.
After geodetic networks are monumented, relevant measurements are taken, and point coordinates for the control points are estimated by the method of least squares.
The automatic generation of volumes bounding the intersection of two implicit surfaces (isosurfaces of real functions of 3D point coordinates) or feature based volumes (FBV) is presented.
As 3D facial features, we compare the use of 3D point coordinates, surface normals, curvature-based descriptors, 2D depth images, and facial profile curves.
First, a restricted but carefully designed set of features, based only on 3D lidar point coordinates and flightline information, is defined as classifier input.
