Measure the object's inertia
#include "dip_measurement.h"
dip_int dip_FeatureGinertiaID ( void )
dip_FloatArray
dip_FeatureGinertiaID returns the ID value of this measurement function, that is registered by Initialise.
This function calculates the inertia (weighted by its grey values) of an object by calculating the eigenvalues of the object's second order moments tensor. This measure only supports 2D and 3D objects. FeatureGinteria supports a measurement parameter (see Measure). If a pointer to a non-zero Boolean is supplied, this function will not only measure the eigenvalues of the second order moments tensor, but also the angles of its eigenvectors.
| Data type | Name | Description |
| dip_Boolean * | angles | Pointer to a Boolean specifying that "eigenangles" should be measured (not yet implemented) |
If any physical dimensions are passed to this function through Measure, only the sample distance along the first dimension is used. All other dimensions are assumed to be sampled the same way. This produces incorrect results for anisotropically sampled images.
