The Conference programme is now ready.


The scope of this research workshop is stochastic simulation and optimisation in image processing (IP), with a particular focus on ill-posed inverse problems that are high-dimensional, have unknown parameters or involve intractable statistical models.

With the recent development of fast and affordable imaging devices, digital images have become fundamental sources of information in science and industry. This has generated an abundance of challenging IP problems as well as the need for more complex image models and new methodologies to use them.

Most modern IP methods rely strongly on statistical theory to solve IP problems, i.e., they use statistical models to describe the image observation process and obtain solutions by performing statistical inference (e.g., computing maximum likelihood or Bayesian estimates). This is mainly achieved by using optimisation techniques related to variational and convex minimisation, and simulation methods such as Markov chain Monte Carlo and Sequential Monte Carlo.

This workshop will bring together world experts on statistical IP, computational statistics and optimisation to discuss the theoretical and methodological challenges facing future statistical IP. The aim is to promote transfer of ideas and methodologies and to identify opportunities for synergy between these important areas, in particular through the integration of stochastic simulation and modern optimisation techniques.

This workshop is organised by Marcelo Pereyra.

The conference programme will include invited plenary talks, contributed research talks and poster presentations. The scope of the workshop includes basic theory and methods and algorithms, and applications in the following areas:
  • Theory, methods and algorithms
    • Stochastic simulation for high-dimensional and IP statistical models.
    • Recent advances in convex optimisation methods for IP.
    • Variational methods for statistical inference in IP.
    • Computational methods for intractable models (e.g., pseudo-marginal MCMC, likelihood-free methods, stochastic gradient MCMC, etc.).
    • General IP methodology for high-dimensional inverse problems with uknown parameters (e.g., blind, semi-blind, unsupervised problems).
  • Application Areas
    • Modelling and methodology for remote sensing applications
    • Modelling and methodology for medical and biological applications

Contributed talks and poster presentations

The call for contributed talks and poster presentation is now closed.


The workshop is funded by SuSTaIn and therefore there is no registration fee. However, numbers are limited so those interested in attending are asked to register in advance.

If you would like to attend the workshop please register using this form.


The workshop is set in the beautiful Goldney Hall Orangery (map) complete with historic gardens and follies . Free wifi is available to all participants.

Goldney Hall Orangery is serviced by the local 8/9 buses with bus stops at Victoria Square and Regent Street.

PLEASE NOTE: The Orangery is located to the side of Goldney Hall on Constitution Hill, and can be entered through a smaller black door as shown here.

Conference dinner

The conference dinner will be held on the evening of Thursday August 28 at the Riverstation,"the best harbourside location in the city!". The conference dinner fee is £40.

Pedestrian directions on how to get to Riverstation (BS1 4RB) from Goldney Hall (BS8 1BH) can be found here.

From other locations, please refer to the map of the restaurant on how to get there.


Directions to Bristol and the University

If you are flying to the UK, you may want to look at the possibility of flying into Bristol airport, which has direct flights from many European cities, including Amsterdam, Geneva, Grenoble, Lisbon, Madrid, Malaga, Paris, Toulouse, which are useful hubs for connections with long-haul flights. Among London airports, Heathrow is the most convenient for transfer to Bristol (you can get from there to Bristol most conveniently by direct National Express bus, or by train). Other possibilities include Birmingham and Cardiff, which have train connections to Bristol. Bristol Temple Meads is the most convenient train station for the University area.
