Book ChapterDOI

Active surface approach for extraction of the human cerebral cortex from MRI

TL;DR: This work presents an active surface method, that extracts the inner and outer cortical boundaries using a combination of different vector fields and a local weighting method based on the intrinsic properties of the deforming surface.
Journal ArticleDOI

BEaST: brain extraction based on nonlocal segmentation technique.

TL;DR: A new robust method dedicated to produce consistent and accurate brain extraction based on nonlocal segmentation embedded in a multi-resolution framework, which provides results comparable to a recent label fusion approach, while being 40 times faster and requiring a much smaller library of priors.
Journal ArticleDOI

DeepQSM - using deep learning to solve the dipole inversion for quantitative susceptibility mapping.

TL;DR: DeepQSM can invert the magnetic dipole kernel convolution and delivers robust solutions to this ill-posed problem, enabling identification of deep brain substructures and provide information on their respective magnetic tissue properties.
Journal ArticleDOI

Using cell nuclei features to detect colon cancer tissue in hematoxylin and eosin stained slides.

TL;DR: A framework for automatic classification of regions of interest (ROI) containing either benign or cancerous colon tissue extracted from whole slide H&E stained images using cell nuclei features showed promising results.
Journal ArticleDOI

A novel semi-automatic segmentation method for volumetric assessment of the colon based on magnetic resonance imaging

TL;DR: The novel semi-automatic segmentation method for quantification of the colon from magnetic resonance imaging (MRI) showed good agreement between observers and may be used in future studies of gastrointestinal disorders to assess colon and fecal volume and colon morphology.
