Fusion of Multi-band Images Using Bayesian Approaches: Beyond Pansharpening

Professor Jean-Yves Tourneret, University of Toulouse

This talk will discuss several methods for fusing high spectral resolution images (such as hyperspectral images) and high spatial resolution images (such as panchromatic images) in order to provide images with improved spectral and spatial resolutions. The first part will be devoted to summarizing the main image fusion methods based on component substitution, multiresolution analysis, Bayesian inference and matrix factorization. The second part will present recent Bayesian fusion strategies exploiting prior information about the target image to be recovered, constructed by interpolation or by using dictionary learning techniques. The resulting Bayesian estimators can be computed by using samples generated by Markov chain Monte Carlo algorithms, by exploiting the efficiency of alternating optimization methods or by solving Sylvester matrix equations.  

Professor Jean-Yves Tourneret 

Jean-Yves TOURNERET (SM’08) received the ingénieur degree in electrical engineering from the Ecole Nationale Supérieure d’Electronique, d’Electrotechnique, d’Informatique, d’Hydraulique et des Télécommunications (ENSEEIHT) de Toulouse in 1989 and the PhD degree from the National Polytechnic Institute from Toulouse in 1992. He is currently a professor in the university of Toulouse (ENSEEIHT) and a member of the IRIT laboratory (UMR 5505 of the CNRS). His research activities are centered around statistical signal and image processing with a particular interest to Bayesian and Markov chain Monte Carlo (MCMC) methods.

He has been the general chair of the CIMI workshop on optimization and statistics in image processing hold in Toulouse in 2013 (with F. Malgouyres and D. Kouamé), of the International Workshop on Computational Advances in Multi-Sensor Adaptive Processing in 2015 (with P. Djuric) and 2019 (with D. Brie). He has been a member of different technical committees including the Signal Processing Theory and Methods (SPTM) committee of the IEEE Signal Processing Society (2001-2007, 2010-2015) and the EURASIP SAT committee on Theoretical and Methodological Trends in Signal Processing (TMTSP). He has been serving as an associate editor for the IEEE Transactions on Signal Processing (2008-2011, 2015-present) and for the EURASIP journal on Signal Processing (2013-present).


Variational Inference and Gaussian Processes

Professor Carl Edward Rasmussen, Department of Engineering, University of Cambridge

Gaussian Processes are a principled, practical, probabilistic approach to learning in flexible non-parametric models and have found numerous applications in regression, classification, unsupervised learning and reinforcement learning. Inference, learning and prediction can be done exactly on small data sets with Gaussian likelihood. In more realistic application with large scale data and more complicated likelihoods approximations are necessary. The variational framework for approximate inference in Gaussian processes has emerged recently as a highly effective and practical tool. I will review and demonstrate the capabilities of this framework.

25 years of particles and other random points

Dr Neil Gordon, The Defence Science and Technology Group, Department of Defence

David J Salmond

Professor Sir Adrian Smith, University of London

A basic form of a Monte Carlo Bayesian recursive filter, which came to be known as a bootstrap filter or a particle filter, was presented 25 years ago.

The key advantage of this filter is that it does not rely on the highly restrictive linear-Gaussian assumptions that underlie the Kalman filter and its variants.

Since then, the particle scheme has been developed, enhanced and applied by researchers in many different fields ranging from the original motivation of target tracking to navigation, robotics, econometrics and weather forecasting.

In this presentation, we shall describe the state of the art in Monte Carlo methods for Bayesian estimation problems in the early 1990’s and indicate how this was extended to dynamic estimation with an evolving state vector.

The circumstances of the development of the filter and some initial test examples will be reviewed with some discussion of the strengths and weaknesses of the approach.
Finally, we shall discuss recent developments, applications and possible future directions.

Neil Gordon received a PhD in Statistics from Imperial College London in 1993. He was with the Defence Evaluation and Research Agency in the UK from 1988-2002 working on missile guidance and statistical data processing. In 2002 he moved to the Defence Science and Technology Organisation in  Australia where he currently leads the Data and Information Fusion research group. In 2014 he became an honorary Professor with the School of Information Technology and Electrical Engineering at the University of Queensland. He is the co-author/co-editor of two books on particle filtering and one on search zone calculations for missing Malaysian airlines flight MH370.


David J Salmond, BSc, DPhil, CEng, FIEE

David Salmond joined the Royal Aircraft Establishment in 1977 as a Scientific Officer. His initial research was on the application of modern control theory to weapon guidance. From this work, together with the missile guidance group, he developed general techniques for tracking and guidance, especially for uncertain systems. In particular, with co-workers, he developed a general Bayesian acquisition / selection scheme for dense and cluttered scenarios. He was also a co-developer of the particle filter method for nonlinear dynamic estimation. The basic scheme has been widely taken up and developed by both the academic community and applied engineers.

He has worked closely with the UK tracking community for many years. He has organised and chaired conferences, served on conference committees and reviews papers for the IEEE, AIAA, IET and other control and data fusion journals. He has published over 150 company reports and open papers.

David retired from QinetiQ as a Senior Fellow in May 2016. He is now a consultant for QinetiQ under the “Friend of QinetiQ” scheme. He has worked for QinetiQ since its foundation in 2001, apart from four years with DSTL (Defence Science and Technology Laboratory) from 2006 to 2010. Prior to 2001, he worked (as a Civil Servant) for QinetiQ’s predecessor institutions.
