Geospatial Data Analysis

[LOGO] Modeling Movement on Transportation Networks Using Uncertain Data
Develop probabilistic network movement models that use as many available data sources as possible to extract meaningful traffic and movement information automatically from the data.
[LOGO] Geometric and Topological Algorithms for Analyzing Road Network Data
Develop algorithms to align realistic trajectories to a network, to reconstruct road networks from trajectory and density data, and to compare data-endowed networks.
[LOGO] Constructing Road Networks from Trajectories
Develop geometric algorithms with quality and performance guarantees for constructing road networks from geo-referenced trajectory data.
[LOGO] Map-Matching and Routing
Algorithms for matching GPS curves to a given roadmap and reactive routing algorithms that adapt to dynamically changing travel-times are essential technical components for Traffic Estimation and Prediction Systems.

Shape Matching

[LOGO] Shape Matching of Curves
Compare geometric shapes described by polygonal curves using adequate distance measures such as the "man-dog" Fréchet distance.
[LOGO] Geodesic Distances for Shapes
Compare shapes on surfaces using shortest distances between points along the surface. This has high applicability in military and GIS applications in which objects traveling on various terrains are involved.
[LOGO] 2D Fréchet Distance
The Frechet distance is a well-suited distance measure for the comparison of surfaces.
[LOGO] Fitting Prehistoric Stone Knives
Archaeologists need to find out which prehistoric stone knives have been chopped from the same core stone.


Computational Biology

[LOGO] Quantifying Morphologic Phenotypes in Prostate Cancer - Developing Topological Descriptors for Machine Learning Algorithms
Develop mathematical and computational tools based on topological descriptors and machine learning in order to distinguish between different morphological types of prostate cancer.
[LOGO] Towards Automated Quantitative Prostate Cancer Diagnosis
Develop quantitative topological descriptors that capture architectural features of prostate glands in pathology images.
[LOGO] Analysis of 2D Electrophoresis Gels
Correctly modeling the shapes of protein spots in 2D electrophoresis gels as well as comparing two and more of such gels is highly important in Computational Proteomics.
[LOGO] Neuron Morphometrics
Semi-automated processing of cultured neuron images.


Graph Drawing

[LOGO] Drawing Graphs with Fat Edges
Drawing graphs with edges of variable thickness. The thickness of an edge is often used as a visualization cue, to indicate importance, or to convey some additional information.
