Removing Local Extrema from Imprecise Terrains
In this paper, we study imprecise terrains, that is, triangulated terrains with a vertical error interval in the vertices. We study the problem of removing as many local extrema (...

Bridge detection in grid terrains and improved drainage enforcement
Bare Earth gridded digital elevation models (DEMs) are often used to extract hydrologic features such as rivers and watersheds. DEMs must be conditioned by removing spurious sinks...

Extremal feature extraction from 3-D vector and noisy scalar fields
We are interested in feature extraction from volume data in terms of coherent surfaces and 3-D space curves. The input can be an inaccurate scalar or vector field, sampled densely...
