QSM Allometric Correction

Nom de classe : SF_StepQSMAllometricCorrection

Description

In Hackenberg et al 2023 we describe input and output parameters of an allometric correction function.

Allometric correction:

With this version you need to execute QSM Detect Wellfit Cylinders before.:
  • [Growth Parameter] VesselVolume .


For full models without removed twigs due to leave removal filter I recommend now parabolic taper fit. But this one does not support automatic estimate average radius and always forces intercept zero while fitting the taper function.
  • The lower the [correction range] , a number larger 1, the more strict is the check: 1.500 . .


If the fitted radius is smaller than 1/ [correction range] times the predicted radius, it is corrected.

If the fitted radius is larger than [correction range] times the predicted radius, it is corrected.
  • If twigs were removed during denoising automatically [estimate average radius] Désactivé . .
