GEODIFF Workshop - GEODIFF 2013

15 Septembre 2012

Catégorie : Conférence internationale

21 - 24 February, 2013 - Barcelona, Spain. In conjunction with the 8th International Joint Conference on Computer Vision, Imaging and Computer Graphics Theory and Applications - VISIGRAPP 2013.



This workshop is organized under the auspices of GEODIFF project funded by French CNRS (PEPS Rupture 2011) and will happen in conjunction with next VISIGRAPP confrences (February 2013, Barcelona).

Main idea of GEODIFF project is to propose original modelling tools of complex diffusion processes that can lead to a better understanding of some usual natural phenomena like spreading of a disease, forest wildfire or plant growing for instance.

That kind of complex diffusion process can be modelled at different scales (micro and macro) using both variationnal approaches or multi agent systems commonly used within the image analysis and understanding community (with applications to image segmentation, restoration, inpainting): If variationnal approaches are well suited to continuous description of processes like diffusion (macro scale), MAS brings a different angle, as the whole process is based on some local heuristics leading the behaviour of the agents (in a micro scale) representing part of the whole process. In this latter case, the phenomenon is hard to model by a continuous physical equation.

From this starting point, GEODIFF project brings together researchers from the Computer Vision community whom main areas of interest are PDE based approaches and MAS in order to propose from the image processing point of view some original diffusion modelling tools which will find applicability in a non-traditionally image processing application areas.


The main aim of this workshop is to bring together researchers who are interested in variationnal methods and in multi agent system in order to (i) reflect on a state-of- the-art on their abilities to model reaction-­-diffusion processes, and (ii) to discuss potential new applications since these two different types of tools are not generally 3 associated with each other whereas such a joint applications can be of primary interest to model complex diffusion process at different scales of the phenomenon.

A second objective of this special session, but not necessarily less important than the first one, is to imagine through this particular application context new tools that will find future applicability in image processing (image restoration or inpainting mainly).
