FeatureP2A

Measure the circularity of the object

SYNOPSIS

#include "dip_measurement.h"

dip_int dip_FeatureP2AID ( void )

FUNCTION

dip_FeatureP2AID returns the ID value of this measurement function, that is registered by Initialise.

This function is a composite measurement function, that uses FeatureSize, FeaturePerimeter, and FeatureSurfaceArea to determine the circularity of an object by calculating: 2D: P2A = perimeter^2 / (4Pi * size) 3D: P2A = surface-area^1.5 / (6 Sqrt(Pi) * size).
