QSM Reverse Pipe Model Filter
Plugin : SimpleForestNom de classe : SF_StepReversePipeModelCorrection
Description
The reverse pipe model order is defined as 1 for leave buildingbricks and should present the radius of the tip at a metabolic scaling unit of the tree.According to the pipe model theory the parent diameter is close to equal to the child cylinder. The combind vessels inside the branch before the branch split up into subclusters of vessels in the side branches. The total vessel sum though remains the same.So if we want to compute other cylinders reverse pipe model order we have to build the root meaned squared sum of the child cylinders reverse pipemodel order. By doing so we have a good linear predictor for the radius. We simply do a robust computation and apply the result line fit prediced radius to all outliers.

Reverse pipe model filter:
- The lower the [correction range] , a percentage number between 0 and 1, the more strict is the check: 0.25 (m). .
- Use as inlier distance for the radius [inlierDistance] 0.015 (m). .
- Split stem from other cylinders and fit individually: Désactivé.
- The twigs have a [min Radius] of 0.0025 (m). .
