Fast Geodesic Active Contours
—We use an unconditionally stable numerical scheme to implement a fast version of the geodesic active contour model. The proposed scheme is useful for object segmentation in imag...

Reengineering Class Hierarchies Using Concept Analysis
The design of a class hierarchy may be imperfect. For example, a class C may contain a member m not accessed in any C-instance, an indication that m could be eliminated, or moved ...

A spectral technique for coloring random 3-colorable graphs (preliminary version)
Let G(3n, p, 3) be a random 3-colorable graph on a set of 3n vertices generated as follows. First, split the vertices arbitrarily into three equal color classes and then choose ev...
