AttenuationCorrection

Attenuation correction algorithm

SYNOPSIS

#include "dip_microscopy.h"

dip_Error dip_AttenuationCorrection ( in, out, fAttenuation, bAttenuation, background, threshold, NA, refIndex, ratio, method )

DATA TYPES

binary, integer, float

FUNCTION

This function implements an attenuation correction using three different recursive attenuation correction algorithms. The RAC-DET algorithm is the most accurate one, since it takes both forward and backward attenuation into account. It is however considerably slower that the RAC-LT2 and RAC-LT1 algorithms which take only forward attenuation into account. These last two algorithms assume a constant attenuation (background) for pixels with an intensity lower than the threshold.
