Measure the object's inertia
#include "dip_measurement.h"
dip_int dip_FeatureGmuID ( void )
dip_FloatArray
dip_FeatureGmuID 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 object's second order moments tensor. This measure only supports 2D and 3D objects. The output tensor is ordered as follows:
2D: xx, xy, yy
3D: xx, xy, xz, yy, yz, zz
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.
