• Shape characterization and structuring through Reeb graph Computation (ShReC): http:
//saturno.ge.imati.cnr.it/ima/smg/shrec-web/SHREC.htm . SHREC is a tool for
characterizing (in the sense of computing maxima, minima and saddles) a surface with or
without boundary with respect to a real function by computing a set of contour levels. Start-
ing from such a characterization, SHREC computes an Extended Reeb graph representa-
tion of the surface, according to the method described in [ 6 ] and [ 17 ].
• Multi-Scale Segmentation of Triangulated Surfaces: http://saturno.ge.imati.cnr
.it/ima/smg/plumber-web/plumber-web.html . is tool implements the multi-scale
curvature characterization of a closed surface described in section 4.2 and automatically
extracts the features that can be described as generalized cylinders or cones.
• SI-HKS & ISC: http://vision.mas.ecp.fr/Personnel/iasonas/descriptors.ht
ml . ese tools are freely available examples of non-rigid shape descriptions that have been
applied to similarity analysis of images and 3D shapes.
• TransforMesh, MeshHOG and MVViewer: http://mvviewer.gforge.inria.fr/ .
is repository contains an implementation of a 3D feature detector (MeshDOG) and a 3D
feature descriptor (MeshHOG) for uniformly triangulated meshes, invariant to changes in
rotation, translation, and scale. Both the detector and the descriptor are able to capture the
local geometric and/or photometric properties.
