Gur, Yaniv | Graph diffusion distance: a difference measure for weighted graphs based on the graph Laplacian exponential kernel | We propose a novel difference metric, called the graph diffusion distance (GDD), for quantifying the difference between two weighted graphs with the same number of vertices. Our approach is based on measuring the average similarity of heat diffusion on each graph. We compute the graph Laplacian expo... | 2013-01-01 | |

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 | Efficient probabilistic and geometric anatomical mapping using particle mesh approximation on GPUs | Deformable image registration in the presence of considerable contrast differences and large size and shape changes presents significant research challenges. First, it requires a robust registration framework that does not depend on intensity measurements and can handle large nonlinear shape variati... | 2011-01-01 | |

Dannhauer, Moritz | Visualizing simulated electrical fields from electroencephalography and transcranial electric brain stimulation: a comparative evaluation | Electrical activity of neuronal populations is a crucial aspect of brain activity. This activity is not measured directly but recorded as electrical potential changes using head surface electrodes (electroencephalogram - EEG). Head surface electrodes can also be deployed to inject electrical current... | 2014-01-01 |
