Medical Image Processing Lab

About Us

The Medical Image Processing Lab (MIPLab) is headed by Dimitri Van De Ville. The lab is jointly between the University of Geneva (Faculty of Medicine, Department of Radiology) and the EPFL (School of Engineering, Institute of Bioengineering). Our research interests are at the interface between signal processing and medical imaging:

• Signal and image processing: wavelets, inverse problems, mathematical imaging, sparsity, pattern recognition.
• Functional imaging: (f)MRI, EEG, PET, laser Doppler optics.

Top News

• April 2012: Hamdi Eryilmaz passed successfully his Ph.D. exam on April 23, 2012. Hamdi's thesis was done in collaboration with MIPLab, in particular the wavelet connectivity techniques. Congratulations Dr. Hamdi!
• March 2012: Congratulations to Dr. Jonas Richiardi who was awarded a prestigious EU Marie-Curie Outgoing Fellowship! Jonas will go to the renowned lab of Prof. Michael Greicius at Stanford University. Good luck in California!
• February 2012: Juliane Britz and Dimitri Van De Ville have been awarded the 2012 Pfizer Research Award (category 'Neurosciences and Diseases of the Central Nervous System') for their work on 'The resting brain: a well-organized chaos with fractal structure'. The award ceremony took place on February 2 at the Metropol in Zurich; photos and videos are available online.
• January 2012: Congratulations to Nora Leonardi who won the Best Poster Award with her work entitled 'Scan-by-scan decoding of cognitive states from fMRI data using whole-brain functional connectivity' during the Alpine Brain Imaging Meeting. Nora's poster is joint work with Jonas Richiardi and Hamdi Eryilmaz.
• January 2012: Dimitri Van De Ville starts his term as Chair of the Biomedical Image and Signal Processing Technical Committee (BISP) of the IEEE Signal Processing Society.
• June 2011: Congratulations to Djano Kandaswamy who successfully defended his Ph.D. Thesis entitled 'Sparse source recovery from boundary measurements using an extension of Prony's method for the Poisson equation'!
• March 2010: Congratulations to Jonas Richiardi who won the Volker-Henn Best Poster Award (category computational neuroscience) with his work 'Inter-subject brain state decoding by classification of fMRI functional connectivity graphs' during the 2010 Annual Meeting of the Swiss Society for Neuroscience. Jonas' poster is joint work with Hamdi Eryilmaz, Sophie Schwartz and Patrik Vuilleumier from LABNIC, University of Geneva.

Paper Highlights

• November 2011: In a new paper entitled A Signal Processing Approach to Generalized 1-D Total Variation, which has appeared in IEEE Transactions on Signal Processing, Isik Karahanoglu proposes a flexible extension of TV regularization.
• September 2011: Our article Nonlocal Means With Dimensionality Reduction and SURE-Based Parameter Selection has appeared in IEEE Transactions on Image Processing. We show that the analytical form of Stein's Unbiased Risk Estimate can be obtained for the Nonlocal Means method, leading to optimal parameter selection. The source is available here.
• May 2011: Our article Decoding Brain States from fMRI Connectivity Graphs, first-authored by Jonas Richiardi, has appeared in the NeuroImage Special Issue on Multivariate Decoding and Brain Reading edited by Prof. John Dylan-Haynes.
• October 2010: Our latest article, authored by Dimitri Van De Ville, Juliane Britz and Christoph Michel, on scale-free dynamics of EEG microstates was just published in the Proceedings of the National Academy of Sciences of the USA. We show scale-free behavior of EEG microstates in the range of 256ms-16sec, explaining the surprising link between fast EEG microstate changes and slow oscillations of resting-state fMRI. This study reveals the fractal organization of spontaneous brain activity as one of the underlying mechanisms of consciousness and cognition.
• July 2010: Congratulations to Juliane Britz whose latest paper in NeuroImage has attracted a lot of attention! Commentaries by Helmut Laufs and Dietrich Lehmann in the same issue accompany the article. The paper is also rated Must Read (8) in the F1000 Database.
