Module: morphometric_features_extraction

Overview

This module provides the implementation of the MorphometricFeatureExtractionPipeline class, used to create the pipeline for the morphometric features extraction. The processes in the pipeline are orchestrated by the do_morphometric_feature_extraction_pipeline_func(), according to the algorithm shown by the following flow chart:
