Description : Automatic feature identification in 2D and 3D
DisPerSE stands for "Discrete Persistent Structures Extractor" and its
main
purpose is the automatic identification of persistent topological
features
such as peaks, voids, walls and in particular filamentary structures
within
sampled distributions in 2D, 3D, and possibly more...
.
Although it was initially developed with cosmology in mind (for the
study of
the properties of filamentary structures in the so called comic web of
galaxy
distribution over large scales in the Universe), the present version is
quite
versatile and should be useful for any application where a robust
structure
identification is required, for segmentation or for studying the
topology of
sampled functions (like computing persistent Betti numbers for
instance).
.
It is able to deal directly with noisy datasets using the concept of
persistence (a measure of the robustness of topological features) and
can work
indifferently on many kinds of cell complex (such as structured and
unstructured grids, 2D manifolds embedded within a 3D space, discrete
point
samples using delaunay tesselation, Healpix tesselations of the sphere,
...).
The only constraint is that the distribution must be defined over a
manifold,
possibly with boundaries.
