As increasing volumes of urban data are captured and become available, new opportunities
arise for data-driven analysis that can lead to improvements in the lives of citizens through …

We advocate the use of point sets to represent shapes. We provide a definition of a smooth
manifold surface from a set of points close to the original surface. The definition is based on …

Scientists are now faced with an incredible volume of data to analyze. To successfully
analyze and validate various hypothesis, it is necessary to pose several queries, correlate …

… Claudio Silva received the PhD degree in computer science from the State University of
New York at Stony Brook in 1996. He is a senior member of technical staff in the Inlormation …

We introduce a robust moving least-squares technique for reconstructing a piecewise smooth
surface from a potentially noisy point cloud. We use techniques from robust statistics to …

The problem of systematically capturing and managing provenance for computational tasks
has recently received significant attention because of its relevance to a wide range of …

VisTrails is a new system that enables interactive multiple-view visualizations by simplifying
the creation and maintenance of visualization pipelines, and by optimizing their execution. It …

We present a fast, memory efficient algorithm that generates a manifold triangular mesh S
passing through a set of unorganized points P R 3 . Nothing is assumed about the geometry, …

We give an overview of VisTrails, a system that provides an infrastructure for systematically
capturing detailed provenance and streamlining the data exploration process. A key feature …

Effectively evaluating visualization techniques is a difficult task often assessed through feedback
from user studies and expert evaluations. This work presents an alternative approach to …
