QSM Median Filter

Plugin : SimpleForest
Nom de classe : SF_StepQSMMedianFilter

Description

If over- or underestimated cylinders ared detected, their radii are adjusted. If a cylinder’s radius is larger or smaller than a percentage based threshold parameter based on the segments median radius it’s radius is set to the median radius.
