Measure the object's area/volume
#include "dip_measurement.h"
dip_int dip_FeatureSizeID ( void )
dip_int, dip_float
dip_FeatureSizeID returns the ID value of this measurement function, that is registered by Initialise.
This function measures the object's size by counting the number of pixels having the same object ID. This measure is the optimal procedure for estimating the area (2D) or volume (3D) of an object with an arbitrary size. The measurement value's unit are in pixels (pixels^2 in 2D, pixels^3 in 3D).
If a dip_PhysicalDimensions parameter is given to Measure, the size of the object is given in physical units, and is a dip_float rather than a dip_int.
