Abstract:
Calculus of Variations provides a sound framework to attack common image processing problems, esp regularization(filtering), registration and segmentation problems. Several researchers have focused on these methods to attack their problems. In this presentation, the basis of these techniques, namely, the Euler-Lagrange Equation will be introduced. We will then talk about Diffusion Filters as they provide an informative link between the EL Eqns derived and the filters designed. The second part of the talk will focus  on 2 projects of VAVlab: Brain Connectivity Analysis and Polyp Enhancement for Virtual Colonoscopy. The presentation will continue with some examples of what is being done around the world. I will conclude with research opportunities/positions at Bogazici University, VAVlab.

Bio:
Burak Acar, PhD, was born in 1972 in Izmir. He  got his BS’94, MS’96 and PhD’00 degrees, all in EE, from Bilkent University. He worked as a research engineer at St. George�s Hospital Medical School, Cardiological Sciences Dept., London, UK (1998-1999) and at Stanford University, Radiological Sciences Laboratory, 3D Lab, Stanford, CA (2000-2003). He joined Bogazici University, EE Dept. in 2003. He is currently consulting Stanford University, 3D Lab. on Virtual Colonoscopy project, collaborating with several universities in Europe as a partner of EU 6th Framework SIMILAR NoE and leading the DRESS (Diagnostic Radiology Expert SystemS) project funded by TUBITAK. His current research interests include computer aided detection/diagnosis systems, virtual medical examinations and shape spaces, as well as related non-medical applications. He has authored 14 journal papers, several conference papers and is a reviewer for several journals.
