Visualizing Patterns in Node-link Diagrams

A. Lambert, F. Queyroi, R. Bourqui
2012 2012 16th International Conference on Information Visualisation  
Pattern discovery plays an important part in the graph analysis process. Good examples are the detection of communities in social networks or the clustering into pathways of metabolic networks.  ...  However, elements may be shared by several clusters, making the patterns entangled. When mining such data, experts are usually interested in both each individual cluster and their overlaps.  ...  The first one consists in clicking on an element of the network and then displaying only the hulls associated to the clusters the element belongs to.  ...

Grouping and Recognition of Dot Patterns with Straight Offset Polygons [article]

Toshiro Kubota
2015 arXiv   pre-print
The straight polygon divides the space into polygons recursively and each polygon can be viewed as grouping of a subset of the dots. The number of polygons generated is O(n).  ...  It then applies the straight polygon transformation to an initial polygon derived from the spanning tree.  ...  This work was supported by the United States National Science Foundation grants CCF-1117439 and CCF-1421734.  ...

Classical Analysis of Phenomenological Potentials for Metallic Clusters

W. D. Heiss, R. G. Nazmitdinov
1994 Physical Review Letters  
The classical trajectories of single particle motion in a Wodds-Saxon and a modified Nilsson potential are studied for axial quadrupole deformation.  ...  Both cases give rise to chaotic behaviour when the deformation in the Woods-Saxon and the l**2 term in the modified Nilsson potential are turned on.  ...  For the Hamilton function of Eq.( 1 ) an appropriate choice of p θ can likewise lead to polygon orbits such as a triangle, square, pentagon, but also a five star, and so forth.  ...

Fast Global Illumination for Visualizing Isosurfaces with a 3D Illumination Grid

David Banks, Kevin Beason
2007 Computing in science & engineering (Print)  
Users who examine isosurfaces of their 3D data sets generally view them with local illumination because global illumination is too computationally intensive.  ...  By storing the precomputed illumination in a texture map, visualization systems can let users sweep through globally illuminated isosurfaces of their data at interactive speeds.  ...  Acknowledgments The neuron data set in Figure 1 was provided by Charles Ouimet and Karen Dietz, Department of Biomedical Sciences, Florida State University. The brain data set in Figure 2  ...

The SVDD classifier partitions the whole space into an inlier region, which consists of the region near the training data, and an outlier region, which consists of points away from the training data.  ...  A small bandwidth leads to overfitting, and the resulting SVDD classifier overestimates the number of anomalies.  ...  Figure 3 displays the data and the scoring result for this data. 2) The refrigerant data, which consists of four clusters [3] .  ...

However, until recently, most of the developed algorithms have focused on simplification and viewing of a single object with a large number of polygons.  ...  Our main contributions include a clustering algorithm tailored towards forming logical groups while respecting roads, a polyline simplification algorithm that maintains boundary facades, and a LOD process  ...  Instead of the traditional vertex/polygon/edge decimation or merging, we aggregate meshes into "logical" clusters and simplify and texture each cluster separately.  ...
