All are welcome to the following talk: Frederic Fol Leymarie Dept of Computing, Goldsmiths College, University of London, UK 3D shape representation via Medial Scaffolds --- theory and applications 2007, május 10 - 10:00 óra BME, Stoczek u. 2. ST épület, III. em 320. Abstract: I will describe elements of a shape language for 3D objects and space. This early version of a shape language builds on the work and collaboration from the fields of Engineering, Applied Mathematics, Computational Geometry, Visual Perception, Arts and the Humanities. It is based on a representation for shapes taking the form of graphs, called "shock graphs" in 2D and "shock and medial scaffolds" in 3D. These incorporate ideas from well-known concepts such as the "medial axis" of H. Blum (pattern recognition), Voronoi diagrams and recent results from Singularity theory. I will illustrate the use of theses graphs in various applications. http://www.doc.gold.ac.uk/morpholingua/ <http://www.doc.gold.ac.uk/morpholingua/> http://doc.gold.ac.uk/~ffl/ <http://doc.gold.ac.uk/%7Effl/> Az eloadaskivonat a kovetkezo cimen is elerheto: http://www.cogsci.bme.hu/EsemHo.php?textfield=&ev=2007&honap=5 Ilona Kovacs
