BrainVisa sulcal extraction and identification pipelines. Sulcal extraction pipeline identifies cerebral hemispheres and cerebellum (A). Next, homotopic erosion and a crevasse detector were used to reconstruct sulcal surface as the medial surface of the two opposing gyral banks (B). Sulcal identification pipeline uses a congregation of 500 artificial neural network‐based pattern classifiers to reconstruct (C) and identify (D) sulcal landmarks in accordance with a learning performed on 26 expertly segmented datasets.
