Meyer, Miriah Dawn | Design activity framework for visualization design | An important aspect in visualization design is the connection between what a designer does and the decisions the designer makes. Existing design process models, however, do not explicitly link back to models for visualization design decisions. We bridge this gap by introducing the design activity fr... | 2014-01-01 | |

Gerig, Guido | Geodesic regression of image and shape data for improved modeling of 4D trajectories | A variety of regression schemes have been proposed on images or shapes, although available methods do not handle them jointly. In this paper, we present a framework for joint image and shape regression which incorporates images as well as anatomical shape information in a consistent manner. Evolutio... | 2014-01-01 | |

Sanderson, Allen Reed | An alternative formulation of lyapunov exponents for computing lagrangian coherent structures | Lagrangian coherent structures are time-evolving surfaces that highlight areas in flow fields where neighboring advected particles diverge or converge. The detection and understanding of such structures is an important part of many applications such as in oceanography where there is a need to predic... | 2014-01-01 | |

Gerig, Guido | Constrained data decomposition and regression for analyzing healthy aging from fiber tract diffusion properties | It has been shown that brain structures in normal aging undergo significant changes attributed to neurodevelopmental and neurodegeneration processes as a lifelong, dynamic process. Modeling changes in healthy aging will be necessary to explain differences to neurodegenerative patterns observed in m... | 2009-01-01 | |

Rosen, Paul Andrew | 2D vector field simplification based on robustness | Vector field simplification aims to reduce the complexity of the flow by removing features in order of their relevance and importance, to reveal prominent behavior and obtain a compact representation for interpretation. Most existing simplification techniques based on the topological skeleton succes... | 2014-01-01 | |

Gerig, Guido | 3D of brain shape and volume after cranial vault remodeling surgery for craniosynostosis correction in infants | The skull of young children is made up of bony plates that enable growth. Craniosynostosis is a birth defect that causes one or more sutures on an infant's skull to close prematurely. Corrective surgery focuses on cranial and orbital rim shaping to return the skull to a more normal shape. Functional... | 2013-01-01 | |

Gerig, Guido | 4D active cut: an interactive tool for pathological anatomy modeling | 4D pathological anatomy modeling is key to understanding complex pathological brain images. It is a challenging problem due to the difficulties in detecting multiple appearing and disappearing lesions across time points and estimating dynamic changes and deformations between them. We propose a novel... | 2014-01-01 | |
