SIAM J. Imaging Sciences, Special Issue on Optimization Many image analysis problems can be formulated as MRF or CRF estimation problems that require minimization of a discrete energy function. Commonly used energy functions are based on models in physics, geometry, or statistics. With some exceptions, however, many formulations correspond to NP-hard optimization problems. Recently there has been a surge in research in image sciences where either known or newly developed combinatorial optimization algorithms were successfully applied to a wide spectrum of problems in imaging. There are several aspects of this development. Some of the new combinatorial algorithms could guarantee globally optimal solutions for certain special cases, and several such special classes were identified in image. Furthermore, new optimization methods with proven performance guarantees have been developed and applied to a much wider spectrum of more difficult imaging problems. Geometric interpretation of discrete energies on N-D grids/complexes have yielded very fruitful connections with continuous models and optimization methods for hyper-surfaces, total variation, or other functionals. In summary, combinatorial optimization techniques applied to image analysis have led to rapid development of a large number of very fast practical optimization algorithms for many imaging problems. We are soliciting original contributions on the theoretical and algorithmic aspects of related discrete optimization techniques, as well as their applications in imaging science. The scope of this special issue includes, but is not limited to: * graph cuts, belief-propagation and message passing, pseudo-boolean optimization, linear and nonlinear binary optimization, primal-dual methods, etc. * applications in image analysis, multiview geometry/reconstruction, optical flows, segmentation, registration, etc. * high-order MRFs * geometric models, convex relaxations, continuous flows Important Dates: Accepting manuscript submissions: March 1 to April 15, 2009 First review completed: July 2009 Revised manuscript due: September 2009 Expected publication date: December 2009/January 2010 Guest Editors: Endre Boros, Rutgers University, The State University of New Jersey Email: Endre.Boros@rutcor.rutgers.edu Yuri Boykov, University of Western Ontario, Canada Email: yuri@csd.uwo.ca Jerome Darbon, University of California Los Angeles Email: jerome@math.ucla.edu Philip Torr, Oxford Brookes University, UK Email: philiptorr@brookes.ac.uk Special Issue Adviser: Andrew Blake, Microsoft Research Cambridge, UK All interested should submit a manuscript and cover letter in PDF format via the SIIMS online submission site at http://siims.siam.org.
