Measure the object's perimeter length
#include "dip_measurement.h"
dip_int dip_FeaturePerimeterID ( void )
dip_FeaturePerimeterID returns the ID value of this measurement function, that is registered by Initialise.
This measures the perimeter of 2D objects by calculating the length of the chaincode of its enclosing border. This function assumes that each object has a single connected border. The used method for measuring the length of the chaincode is optimal for circles, and for a collection of objects that are randomly orientated, see the referenced literature for detailed.
