Chers collègues, La prochaine session du séminaire Performance et Généricité du LRDE (Laboratoire de Recherche et Développement de l'EPITA) aura lieu le Mercredi 16 novembre 2011 (14h-16h). Au programme: * 14h: Interactive 2D and 3D Segmentation with ilastik -- Ullrich Köthe http://www.ilastik.org The ilastik system developed by our group uses machine learning and simple interaction techniques to empower users without special image processing expertise to segment and analyze their 2- and 3-dimensional image data on their own. It offers a number of easy-to-use workflows for various common analysis tasks. The talk will present two of these workflows (“interactive classification” and “region carving”), going from an online demonstration of the high-level user experience down to the algorithmic and software design details. Special emphasis will be put on aspects of genericity and parallelization which facilitate convenient adaptation of basic building blocks to different contexts without loss of performance. Examples from challenging biological applications will illustrate our system's capabilities. -- Ullrich Köthe is a senior researcher in the Multidimensional Image Processing Group at the Interdisciplinary Centre for Scientific Computing of the University of Heidelberg, Germany, where he heads advanced research on image and data analysis for industry and the life sciences. Formerly, he was with the Cognitive Systems Group at the University of Hamburg (1999-2007) and with the Fraunhofer-Institute for Computer Graphics in Rostock (1992-1999). -- Ullrich Köthe's main field of research is the development of user-friendly image analysis methods. He is interested in all techniques that facilitate genericity and re-usability, from machine learning and probabilistic modeling to generic programming and empirical performance evaluation. Dr. Köthe is the originator and maintainer of the open-source image analysis library VIGRA and co-developer of the interactive ilastik toolkit, which have been designed to put these ideas into practice.
