Istar: A raster representation for scalable image and volume data (2009)
Joe Kniss, Warren Hunt, Kristin Potter, Pradeep Sen
Abstract — Topology has been an important tool for analyzing scalar data and flow fields in visualization. In this work, we analyze the topology of multivariate image and volume data sets with...

EUROGRAPHICS 2008 / K. Mania and E. Reinhard Short Papers Video Carving (2008)
We present a technique for summarizing a video into a short segment, while preserving the important events in the original. While many techniques remove whole frames from the video stream when...
21 2D texture mapping: real-time perceptual surface roughening (2008)
Sylvia C. Pont, Pradeep Sen, Pat Hanrahan
Figure 1: Cylinders with an orthogonally-projected plaster texture. In the first cylinder the texture is only warped, while in the second we have added diffuse shading as is conventionally done for...

P.: Shadow silhouette maps (2003)
The most popular techniques for interactive rendering of hard shadows are shadow maps and shadow volumes. Shadow maps work well in regions that are completely in light or in shadow but result in...
