OMSMO Project: Oriented Matroids for Shape Modeling

Preliminary page under construction...


The general research project has been initiated by Emeric Gioan, a specialist of oriented matroid theory. It is developed at the LIRMM, especially together with Gérard Subsol, a specialist of medical imaging. Beyond some theoretical/combinatorial questions, the aim of the project is to develop a combinatorial morphometry method. It consists in encoding 3D landmark-based models with their associated oriented matroid, and in using this combinatorial structure in order to analyse/classify/characterize the structural shapes of the models. Applications notably concern natural sciences such as medical imaging and biological anthropology. The first results have been obtained together with Kevin Sol (doctoral student) and using experimental data given by various researchers from the application fields (José Braga, Jacques Treil, Yann Heuzé, Joan Richstmeier). Various research directions from mathematical/computational/applied viewpoints are in progress with those researchers and others...

OMSMO Software

A software is currently developed at the LIRMM by Emeric Gioan and Boris Albar (engineer). Some preliminary work have consisted in C programs by Kevin Sol that have already been used in the above paper on experimental data, and on a Java visualization applet made by a group of students from University of Montpellier. It is also supported by LIRMM engineers Joël Maizit and Martine Hornby for the integration into the LIRMM server. It will allow worldwide researchers to test our mathematical/computational method on their data (asap).
