Gerig, Guido | Multiscale medial shape-based analysis of image objects | Medial representation of a three-dimensional (3-D) object or an ensemble of 3-D objects involves capturing the object interior as a locus of medial atoms, each atom being two vectors of equal length joined at the tail at the medial point. Medial representation has a variety of beneficial properties,... | | 2003-01-01 |

Gerig, Guido | Parametric regression scheme for distributions: analysis of DTI fiber tract diffusion changes in early Brain Development | Temporal modeling frameworks often operate on scalar variables by summarizing data at initial stages as statistical summaries of the underlying distributions. For instance, DTI analysis often employs summary statistics, like mean, for regions of interest and properties along fiber tracts for populat... | | 2014-01-01 |

Gerig, Guido | Population-based fitting of medial shape models with correspondence optimization | A crucial problem in statistical shape analysis is establishing the correspondence of shape features across a population. While many solutions are easy to express using boundary representations, this has been a considerable challenge for medial representations. This paper uses a new 3-D medial model... | | 2007-01-01 |

Gerig, Guido | Regional gray matter growth, sexual dimorphism, and cerebral asymmetry in the Neonatal Brain | Although there has been recent interest in the study of childhood and adolescent brain development, very little is known about normal brain development in the first few months of life. In older children, there are regional differences in cortical gray matter development, whereas cortical gray and wh... | | 2007-01-01 |

Gerig, Guido | Reduced relationship to cortical white matter volume revealed by Tractography-based segmentation of the corpus callosum in young children with developmental delay | Objective: The corpus callosum is the primary anatomical substrate for inter-hemispheric communication, which is important for a range of adaptive and cognitive behaviors in early development. Previous studies that have measured the corpus callosum in developmental populations have been limited by t... | | 2006-01-01 |

Gerig, Guido | Spatiotemporal modeling of distribution-valued data applied to DTI tract evolution in infant neurodevelopment | This paper proposes a novel method that extends spatiotemporal growth modeling to distribution-valued data. The method relaxes assumptions on the underlying noise models by considering the data to be represented by the complete probability distributions rather than a representative, single-valued su... | | 2013-01-01 |

Gerig, Guido | Spatio-temporal analysis of early brain development | Analysis of human brain development is a crucial step for improved understanding of neurodevelopmental disorders. We focus on normal brain development as is observed in the multimodal longitudinal MRI/DTI data of neonates to two years of age. We present a spatio-temporal analysis framework using Gom... | | 2010-01-01 |

Gerig, Guido | Spatial intensity prior correction for tissue segmentation in the developing human brain | The degree of white matter (WM) myelination is rather inhomogeneous across the brain. As a consequence, white matter appears differently across the cortical lobes in MR images acquired during early postnatal development. At 1 year old specifically, the gray/white matter contrast of MR images in pref... | | 2011-01-01 |

Seyedhosseini Tarzjani, Seyed Mojtaba | A workflow for the automatic segmentation of organelles in electron microscopy image stacks | Electron microscopy(EM) facilitates analysis of the form,distribution, and functional status of key organelle systems in various pathological processes,including those associated with neurodegenerative disease.Such EM data often provide important new in sights into the underlying disease mechanisms.... | | 2014-01-01 |

Gerig, Guido | Abnormal vessel tortuosity as a marker of treatment response of malignant gliomas: preliminary report | Despite multiple advances in medical imaging, noninvasive monitoring of therapeutic efficacy for malignant gliomas remains problematic. An underutilized observation is that malignancy induces characteristic abnormalities of vessel shape. These characteristic shape abnormalities affect both capillari... | | 2004-01-01 |

Solomon, Douglas Kip | Bayesian evaluation of groundwater age distribution using radioactive tracers and anthropogenic chemicals | The development of a Bayesian modeling approach for estimation of the age distribution of groundwater using radioactive isotopes and anthropogenic chemicals is described. The model considers the uncertainties associated with the measured tracer concentrations as well as the parameters affecting the ... | | 2012-01-01 |

Gerig, Guido | Automatic corpus callosum segmentation using a deformable active Fourier contour model | The corpus callosum (CC) is a structure of interest in many neuroimaging studies of neuro-developmental pathology such as autism. It plays an integral role in relaying sensory, motor and cognitive information from homologous regions in both hemispheres. We have developed a framework that allows auto... | | 2012-01-01 |

Gerig, Guido | Closed and open source neuroimage analysis tools and libraries at UNC | The emergence of open-source libraries and development tools in the last decade has changed the process of academic software development in many ways. In medical image processing and visualization this change is especially evident, also because open source projects are actively furthered by grant fu... | | 2006-01-01 |

Gerig, Guido | A structural MRI study of human brain development from birth to two years | Brain development in the first 2 years after birth is extremely dynamic and likely plays an important role in neurodevelopmental disorders, including autism and schizophrenia. Knowledge regarding this period is currently quite limited. We studied structural brain development in healthy subjects from... | | 2008-01-01 |
