Gerig, Guido | Computational anatomy to assess longitudinal trajectory of brain growth | This paper addresses the challenging problem of statistics on images by describing average and variability. We describe computational anatomy tools for building 3-D and spatio-temporal 4-D atlases of volumetric image data. The method is based on the previously published concept of unbiased atlas bui... | 2006-01-01 | |

Gerig, Guido | Correspondence evaluation in local shape analysis and structural subdivision | Regional volumetric and local shape analysis has become of increasing interest to the neuroimaging community due to the potential to locate morphological changes. In this paper we compare three common correspondence methods applied to two studies of hippocampal shape in schizophrenia: correspondence... | 2007-01-01 | |

Gerig, Guido | Discrimination analysis using Multi-object statistics of shape and pose | A main focus of statistical shape analysis is the description of variability of a population of geometric objects. In this paper, we present work towards modeling the shape and pose variability of sets of multiple objects. Principal geodesic analysis (PGA) is the extension of the standard technique ... | 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 | Statistical group differences in anatomical shape analysis using Hotelling T2 Metric | Shape analysis has become of increasing interest to the neuroimaging community due to its potential to precisely locate morphological changes between healthy and pathological structures. This manuscript presents a comprehensive set of tools for the computation of 3D structural statistical shape anal... | 2007-01-01 | |

Gerig, Guido | Statistical shape analysis of brain structures using spherical wavelets | We present a novel method of statistical surface-based morphometry based on the use of non-parametric permutation tests and a spherical wavelet (SWC) shape representation. As an application, we analyze two brain structures, the caudate nucleus and the hippocampus, and compare the results obtained to... | 2007-01-01 | |

Gerig, Guido | Statistical shape analysis of Multi-Object complexes | An important goal of statistical shape analysis is the discrimination between populations of objects, exploring group differences in morphology not explained by standard volumetric analysis. Certain applications additionally require analysis of objects in their embedding context by joint statistical... | 2007-01-01 | |

Gerig, Guido | Statistics of populations of images and its embedded objects: driving applications in neuroimaging | Work in progress towards modeling shape statistics of multi-object complexes is presented. Constraints defined by the set of objects such as a compact representation of object shape relationships and correlation of shape changes might have advantages for automatic segmentation and group discriminati... | 2006-01-01 |
