Compute the chord lengths of the different phases
#include "dip_analysis.h"
dip_Error dip_ChordLength ( object, mask, dist, probes, length, sampling )
binary, integer
This function computes the chord lengths of the different phases in object. If object is a binary image, the image is a regarded as a two phase image. In case object is of the integer type, the image is regarded as a labeled image, with each integer value encoding a phase. Optionally a mask image can be provided to select which pixels in object should be used to compute the chord lengths. The probes variable specifies how many random point pairs should be drawn to compute the lengths. Length specifies the maximum correlation length. The correlation function can be computed using a random (DIP_CORRELATION_ESTIMATOR_RANDOM) or grid method (DIP_CORRELATION_ESTIMATOR_GRID), as specified by sampling.
