Optimal transport :
Theory and Applications
to cosmological Reconstruction and Image processing
International workshop Optimization and stochastic methods for spatially distributed information
St Petersburg, Russia, May 11–15, 2010
Optimal transport and image processing in geoinformatics and computer vision: The emphasis of the present workshop is on applications in image processing, computer vision, astroinformatics, and geoinformatics.
These fields have already benefitted from fruitful application of numerical transport optimization techniques (referred to, e.g., as “earth mover's distance” in the image processing community). The PDE models arising in transport optimization, such as the Monge–Ampère and Hamilton–Jacobi–Bellman equations, are useful mathematical tools whose potential deserves further exploration. We are also interested in the perspective on optimal transportation techniques and their application to processing of spatially sistributed information offered by modern statistical physics.
This is the second workshop in a series of rencontres supported by the OTARIE project. Our aim is to confront the mathematical community (including, but not limited to, specialists in transport optimization) with interesting applied fields. The web page for the previous workshop of the series, featuring to applications in cosmology and held at Technion, Haifa, in March 2009, is available here.
This page contains a list of participants, photos, and program of the conference. Slides of talks are clickable form the list of talk titles in the program. There is also some practical information regarding the venue, accommodation, and getting around the city.

All talks will last 1 hr including discussion, and should be suitable for the diverse audience of the workshop.
Click to download the slides wherever available. All slides are in the PDF format unless specified otherwise.
The conference venue is provided by the Euler International Mathematics Institute (EIMI). The conference room is equipped with a chalk blackboard, an overhead projector and a video projector.
Your local contacts are Dr Eugene Stepanov and Program Coordinator Nadia Zalesskaya of the EIMI (email firstname.lastname@example.org, tel/fax +7-812-234-0574 during office hours). It is also a good idea to copy your conference-related email to Dr Andrei Sobolevski (Skype name andrei.sobolevskii). If you are reading this page, Stepanov's and Sobolevski's emails should probably be already known to you. Both are usually available in Google when online)
Most participants coming from outside St Petersburg will be accommodated at Hotel Andersen, a three-star hotel in a walking distance from the conference venue at EIMI and not far from the nearest metro station, Petrogradskaya. Click the link below the following map to see a larger one.

From the Pulkovo-II Airport: Take bus 13 or a minibus (numbers 3, 13, 113, or 213) near the Arrivals hall. Exit at the large plaza with fountains (this web page in Russian has some photos) and take the metro from the Moskovskaya metro station to the Petrogradskaya station (same line, blue).
From the Petrogradskaya metro station to the hotel: the simplest is just to walk (10–15 minutes). Alternatively you can take two stops by trolleybus 34 or by bus 1 or 46, or by minibuses 46, 76, 127, 252, 298, 346 (in a minibus you should ask to stop at Ulitsa Chapygina).

Important: in public transport, as well as elsewhere in the city, you will need roubles in cash! 10-rouble bills and 1- or 2-rouble coins are ideal, and 50-rouble bills still work (bus drivers strongly prefer to have exact change). One metro trip is 22 roubles: buy coin-shaped tokens at a “kassa” at any metro station, or get a rechargeable magnetic card (30 roubles, reimbursable when you return the card; cards are sold and recharged in special machines located at most metro stations). Normal bus/trolleybus ticket is 19 roubles, and minibuses are operated by private companies and cost from 26 to 30 roubles.
Be sure also to check out the helpful TripAdvisor page on St Petersburg as well as a local tourist web site in English.
